Technical Regulations

Hydrogen fuel cell vehicles are expected to play an important role in the future and thus have improved significantly over the past years. Hydrogen fuel cell motorcycles with a small container for compressed hydrogen gas have been developed in Japan along with related regulations. As a result, national regulations have been established in Japan after discussions with Japanese motorcycle companies, stakeholders, and experts. The concept of Japanese regulations was proposed internationally, and a new international regulation on hydrogen-fueled motorcycles incorporating compressed hydrogen storage systems based on this concept are also established as United Nations Regulation No. 146. In this paper, several technical regulations on hydrogen safety specific to fuel cell motorcycles incorporating compressed hydrogen storage systems are summarized. The unique characteristics of these motorcycles, e.g., small body, light weight, and tendency to overturn easily, are considered in these regulations.

Safety Features

On-board storage and handling of hydrogen continues to be a major challenge on the road to the widespread commercialization of hydrogen fuel cell vehicles. QUANTUM Fuel Systems Technologies WorldWide, Inc. (QUANTUM) is developing a number of advanced technologies in response to the demand by its customers for compact, lightweight, safe, robust, and cost-effective hydrogen fuel systems. QUANTUM approaches hydrogen storage and handling as an engineered system integrated into the design of the vehicle. These engineered systems comprise advanced storage, regulation, metering, and electronic controls developed by QUANTUM. In 2001, QUANTUM validated, commercialized, and began production of lightweight compressed hydrogen storage systems. The first commercial products include storage technologies that achieved 7.5 to 8.5 percent hydrogen storage by weight at 350 bar (5,000 psi). QUANTUM has also received German TUV regulatory approval for its 700 bar (10,000-psi) TriShield10™ hydrogen storage cylinder, based on hydrogen standards developed by the European Integrated Hydrogen Project (EIHP). QUANTUM has patented an In-Tank Regulator for use with hydrogen and CNG, which have applications in both fuel cell and alternative fuel vehicle markets. To supplement the inherent safety features designed into the new 700 bar storage tank, QUANTUM’s patented 700 bar In-Tank Regulator provides additional safety by confining the high pressure in the tank and allowing only a maximum delivery pressure of 10 bar (150-psi) outside the storage system. This paper describes initial applications for these hydrogen fuel systems, which have included fuel cell automobiles, buses, and hydrogen refueling stations.

Scientific Accomplishment

The problem of environmental pollution has become worse and worse as the demand for energy has grown. An important aim of modern science is a diligent search for non-polluting methods of energy production. The fuel cell is one of the most important power sources devised in the 21st century and has all the necessary characteristics for environmental protection. The technology is pollution-free and highly efficient, converting the chemical energy of hydrogen gas directly into electricity. The fuel cell can be regarded as a small-scale power plant. The flow of electricity will continue as long as there is a supply of hydrogen. At present the storage of hydrogen is the most important consideration and there is not much information about fuel cells readily available at this time. This study concerns the development of 'The Hydrogen Fuel Cell generates Electricity Module' and demonstrates this in the design and use of a toy. A systemized analysis of power operation using existing fuel cell products and a setup of 'The Hydrogen Fuel Cell generates Electricity Module' was made. The Taguchi Method was used to arrive at the best parameter combination between fuel cell and toy. The best combination of parameters obtained in this experiment provides a power line voltage of 3.0V. An assessment was made of the arrangement of a non-pressurized single fuel cell that will best suit the requirements for use in the toy whale used in this work. This will instill feelings of personal scientific accomplishment and give the toy making industry a new look at the same time. We hope this can be applied on a larger scale in the future to provide non-polluting power for many such applications.

Abstract Presented here is a novel system that uses an aluminum-based fuel to continuously produce electrical power at the kW scale via a hydrogen fuel cell. This fuel has an energy density of 23.3 kWh/L and can be produced from abundant scrap aluminum via a minimal surface treatment of gallium and indium. These additional metals, which in total comprise 2.5% of the fuel’s mass, permeate the grain boundary network of the aluminum and disrupt its oxide layer, thereby enabling the fuel to react exothermically with water to produce hydrogen gas and aluminum oxyhydroxide, an inert and valuable byproduct. To generate electrical power using this fuel, the aluminum-water reaction is controlled via water input to a reaction vessel in order to produce a constant flow of hydrogen, which is then consumed in a fuel cell to produce electricity. As validation of this power system architecture, we present the design and implementation of two example systems that successfully demonstrate this approach. The first is a 3 kW emergency power supply and the second is a 10 kW power system integrated into a BWM i3 electric vehicle.

Alkaline Water Electrolysis

Electrical grid expansion onto remote areas is often not cost-effective and/or technologically feasible. Thus, isolated electrical systems are preferred in such cases. This paper focuses on a hybrid photovoltaic (PV)-hydrogen/fuel cell (FC) system which basic components include a PV, a FC, alkaline water electrolysis and a hydrogen gas tank. To increase the response rate, supercapacitors or small batteries are usually employed in such systems. This study focuses on the dynamics of the system. In the suggested structure, the PV is used as the main source of power. The FC is connected to the load in parallel with the PV by a transducer in order to inject the differential power while reducing power generation in relation to power consumption. An electrolyzer is used to convert the surplus power to hydrogen. This study studies a conventional hybrid photovoltaic-hydrogen/fuel cell system to evaluate different loading behaviors. Software modeling is done for the suggested hybrid system using MATLAB/SIMULINK.
