To accelerate the development of the hybrid transportation system, there is a need to set up an infrastructure for the hybrid vehicle battery recharging at parking lots of universities as test grounds for this technology. This work focuses on setting up or implementing a pilot recharging network at Kettering University’s main parking lot with a capacity of over 500 vehicles. As the society is transitioning from the fossil fuel powered vehicles to hybridized systems, recharging outlet from fuel cell, solar and wind turbines sources should be in place to facilitate the transfer by 2015. This project details the infrastructural design using fuel cell energy from the Center for Fuel Cell Research of the University for setting up 50 pilot recharging outlets at the parking lot behind the Mott Engineering Building to recharge hybrid vehicles in the main parking lot of the University. The current resources at the Center include a 5 kW SOFC test station, a 4.4 kW Ballard LT-PEM fuel cell mounted on a 5 kW test stand and 1.5 kW high temperature HT-PEM produced by GEI LLC. The use of solar energy during the day is also considered. The applicable codes and standards regarding such installations are reviewed.

A 5 kW proton exchange membrane fuel cell (PEMFC) with a reformer has been installed and tested at the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Brazil, aiming the experimental determination of its performance and co-generation potential to increase the fuel chemical energy usage. The unit uses a fuel processor to convert energy from natural gas into hydrogen rich reformate. The fuel cell is totally instrumented, supplying data for calculating the overall system efficiency (total efficiency), reformer efficiency, stack efficiency, conversion efficiency (DC/AC), and co-generation potential, at previously set up output powers of 2,5 kW and 4 kW. The paper details the equations required for calculating the parameters, both theoretically, from thermodynamics and electrochemics points of view, and experimentally, from mass and energy balances, comparing the results. Steady state data were taken at 13 different days, resulting in reformer, stack, conversion and total average efficiencies, together with the calculated standard deviation. It was also found that the energy loss in the reformer and in the stack are approximately the same. The co-generation potential was estimated by calculating the heat rejected by the stack and the heat rejected in the reformer, giving a value of 67,5% and 68,9%, respectively for 2,5 kW and 4 kW. Therefore, co-generation can substantially reduce the fuel cell energy cost, and thus increasing the feasibility of its use.

Fuel Cell Hybrid

In order to improve fuel economy and enhance operating efficiency of fuel cell hybrid vehicles (FCHVs), fuzzy logic control (FLC) strategies are available and suggested for adoption. In this paper, the powertrain of a fuel cell hybrid vehicle is designed and the parameters of the motor, battery, and fuel cell are calculated. The FLC strategy and the power following control (PFC) strategy are designed for the studied FCHV. A secondary development for Advanced Vehicle Simulator (ADVISOR) is implemented based on the standard driving cycles, and a Chinese typical city driving cycle is imported. Simulation results demonstrate that the proposed FLC strategy is more valid and reasonable than the traditional PFC strategy. The proposed FLC strategy affects the vehicle characteristics significantly and contributes to better performance in four aspects: fuel economy, efficiency of battery and fuel cell system, battery state of charge (SOC), and battery life. Hence, the FLC strategy is more suitable for the energy management strategy for fuel cell and battery hybrid vehicles.

AbstractRecently, the German Federal Government made the consequential decision to change its energy program. This not only as a result of the decision to shut down the existing nuclear power plants within the next few years, but also due to vital challenges like climate change and security of energy supply. The shift in the energy-technology paradigm from fossil fuel technologies to regenerative energies constitutes a major technical process but also new economic and social constellations.This paper focuses on hydrogen and fuel cell technologies in Germany. The institutional set up in this field is analysed and the new organizational actors are identified who have actively lobbied towards a political consensus. However, the experts in this field could not attain the required leadership in the public discourse on these technologies. It seems that an attractive guiding vision of a post-fossil energy future and a broad acceptance in daily use would have been major prerequisites for such leadership.

Abstract The growing number of foreign applicants looking forward to getting education in Ukrainian medical universities makes us find the ways how to improve and make effective the pre-professional training system of foreign medical applicants for further education. The article deals with the issues of the history of formation and development of the preprofessional training system of foreign medical applicants in Ukraine. On the ground of the electronic databases of the official websites of higher educational establishments, the data on years of opening first offices of the dean, departments and preparatory faculties for foreign medical applicants in Ukrainian medical universities are analyzed and systematized. Also the data on the setting up preparatory faculties at other universities who carry out licensed training of foreign students of the medical profile are presented. The data on the operating and management of such institutions in the system of the University administration are generalized. It’s revealed that during the years of its functioning the pre-professional training has changed, in particular the system was commercialized and the institutions involved in training foreign applicants have been reorganized. The modern trends in teaching foreign medical students at the preparatory faculties of the Ukrainian medical universities are displayed. Based on the analysis of the data it is concluded that the system of the pre-professional training of foreign medical applicants was set up in the 50s-60s years of the twentieth century. During this time, some positive experience in the preparation of future international medical specialists has been gained. The system of the pre-professional training of foreign medical applicants has been comprehensively improved and an effective system of managing foreign medical applicants has been created.

A hybrid system based on an existing recuperated microturbine and a pre-commercially available high temperature tubular solid oxide fuel cell is modeled in order to study its performance. Individual models are developed for the microturbine and fuel cell generator and merged into a single one in order to set up the hybrid system. The model utilizes performance maps for the compressor and turbine components for the part load operation. The full and partial load exergetic performance is studied and the amounts of exergy destruction and efficiency of each hybrid system component are presented, in order to evaluate the irreversibilities and thermodynamic inefficiencies. Moreover, the effects of various performance parameters such as fuel cell stack temperature and fuel utilization factor are investigated. Based on the available results, suggestions are given in order to reduce the overall system irreversibility. Finally, the environmental impact of the hybrid system operation is evaluated.
