A novel method of using a liquid phase oxidizer in fuel cell applications has been discovered by researchers at UC Davis. This paper outlines potential implications for improving heat transfer and catalytic activity with this method. Experimental data have been collected and the results show that the proposed method of using liquid phase oxidizer does indeed allow operation of PEM fuel cell systems. Data indicate an improvement in overvoltage at low current but also clearly indicate a severely limited concentration polarization region with non-regenerated fluid. The preliminary data indicate the physical feasibility of the method but also show that more research and development is required.

The Heat Transfer Coefficient

Purpose The purpose of this paper is to investigate the effects of hydrogen humidity on the performance of air-breathing proton exchange membrane (PEM) fuel cells. Design/methodology/approach An efficient mathematical model for air-breathing PEM fuel cells has been built in MATLAB. The sensitivity of the fuel cell performance to the heat transfer coefficient is investigated first. The effect of hydrogen humidity is also studied. In addition, under different hydrogen humidities, the most appropriate thickness of the gas diffusion layer (GDL) is investigated. Findings The heat transfer coefficient dictates the performance limiting mode of the air-breathing PEM fuel cell, the modelled air-breathing fuel cell is limited by the dry-out of the membrane at high current densities. The performance of the fuel cell is mainly influenced by the hydrogen humidity. Besides, an optimal cathode GDL and relatively thinner anode GDL are favoured to achieve a good performance of the fuel cell. Practical implications The current study improves the understanding of the effect of the hydrogen humidity in air-breathing fuel cells and this new model can be used to investigate different component properties in real designs. Originality/value The hydrogen relative humidity and the GDL thickness can be controlled to improve the performance of air-breathing fuel cells.
