Special Issue Information

Dear Colleagues,

Sharing the merits of zero emissions, high power density and rapid startup, proton exchange membrane fuel cell is regarded as the most promising candidate for next-generation power sources for transportation and portable applications.

Designing a cost-effective, high-performance proton exchange membrane fuel cell requires the proper organization of the transport of the reactants of hydrogen and oxygen, the product of water, and the generated heat. This Special Issue aims to provide a platform to exchange the recent progress on water–thermal management and gas (especially hydrogen) detection technologies for proton exchange membrane fuel cells. Research areas may include (but are not limited to) the following: water transport mechanism, heat transport mechanism, membrane design and fabrication, transport property measurement, and novel hydrogen detection technology. In this Special Issue, both original research articles and reviews are welcome.

We look forward to receiving your contributions.

Abstract

Investigating the oxygen transport law within the Membrane Electrode Assembly at intermediate temperatures (80–120 °C) is crucial for enhancing fuel cell efficiency. This study analyzed the resistance to oxygen transport within the Membrane Electrode Assembly at intermediate temperatures using limiting current density and electrochemical impedance spectroscopy. The study findings reveal that, as temperature progressively increases, the Ostwald ripening effect leads to a 34% rise in the local oxygen transport resistance (R_local) in relation to the pressure-independent resistance (R_np) within the cathode catalytic layer. Concurrently, the total transport resistance (R_total) decreases from 27.8% to 37.5% due to an increase in the gas diffusion coefficient and molecular reactivity; additionally, there is a decrease in the amount of liquid water inside the membrane electrode. A three-dimensional multiphysics field steady-state model was also established. The model demonstrates that the decrease in oxygen partial pressure can be mitigated effectively by increasing the back pressure at intermediate temperatures to ensure the cell’s performance.
