A data-driven optimal control method for an air supply system in proton exchange membrane fuel cells (PEMFCs) is proposed with the aim of improving the PEMFC net output power and operational efficiency. Moreover, a marginal utility-based double-delay deep deterministic policy gradient (MU-4DPG) algorithm is proposed as a an offline tuner for the PID controller. The coefficients of the PID controller are rectified and optimized during training in order to enhance the controller’s performance. The design of the algorithm draws on the concept of marginal effects in Economics, in that the algorithm continuously switches between different forms of exploration noise during training so as to increase the diversity of samples, improve exploration efficiency and avoid Q-value overfitting, and ultimately improve the robustness of the algorithm. As detailed below, the effectiveness of the control method has been experimentally demonstrated.

Low temperature fuel cells such as proton exchange membrane fuel cells are being currently developed to run cars and buses. Water management in these fuel cells is a key issue that needs to be adequately addressed for rapid development of the technology. The fuel cell reaction creates water that is typically carried away by the incoming air. However, at part load operations when the required air supply is lower, water droplets may fully block the air supply channels, leading to inefficient fuel cell operation. A solution to this problem is proposed taking a cue from tiny insects known as aphids that live inside plants. They excrete a watery substance called honeydew and get rid of this water using wax by encapsulating it into tiny droplets. In the present study, air-water interaction in a minichannel is studied in the presence of powdered wax. Air is forced into the channel inlet and water is pumped through a hole on the top wall of the channel. The movement of water inside the channel at different air velocities and water flow rates is recorded using a high-speed camera. Results indicate that the water droplets and slugs formed inside the channel are removed more rapidly in the presence of powdered wax. At the highest water flow rate and lowest air velocity used in this study the unwaxed channel gets completely flooded while the slugs of water continued to move forward in the waxed channel. Different two-phase flow regimes have been identified and plotted in both the waxed and unwaxed channels.

The dynamic model of the air supply system for a proton exchange membrane fuel cell (PEMFC) stack is developed in this paper. The PEMFC cathode/anode, and air supply system including a compressor, a motor, and a supply manifold(SM) are modeled; the compressor performance map is identified based on a fuzzy neural network (FNN). The PEMFC air supply system is simulated by using Matlab environment. The simulation results show that the proposed models can effectively represent the dynamic characteristics of the system components, and lay the foundation for the control strategy design of the PEMFC air supply flow.
