## Abstract This study focuses on the performances of proton exchange membrane fuel cells (PEMFCs) at 80 and 90βΒ°C with feeds of varying degrees of humidification. The results show that ohmic resistance of the solid electrolyte decreases as the current density is raised because of the back diffusio
A mathematical model was developed to describe the performance of hydrogen electrode catalyst particles that are bonded to the proton exchange membrane of a hydrogen-bromine fuel cell. Macrohomogeneous porous electrode theory was applied to the catalyst particles. Fundamental equations were used to
