Optimization of a Reversible Fuel Cell Oxygen Electrode Composition and Structure

Abstract

The optimization of the structure and composition of the oxygen electrode catalytic layer in polymer electrolyte membrane (PEM) unitized regenerative fuel cell (URFC) is described. The theoretical model described the transfer processes in catalytic layer is modified which allows to consider the Pt and Ir content influence on the catalytic layer performance at different URFC operating modes. The model calculations are verified through the URFCcell testing.
