Simple model for the estimation of isothermal fuel cell performance

Abstract

Prediction of the performance of fuel cells is important from various viewpoints. Mostly, extended computer codes are used for this purpose. Such codes predict the performance in isothermal or adiabatic conditions, using basic physical properties, models for porous cell components to calculate polarizations and models for mass and heat transfer. Unfortunately, these codes are not always suited to relatively simple experimental, modelling or engineering purposes. This contribution, however, describes a simple analytic tool for the prediction of isothermal fuel cell voltages depending on system parameters, like temperature, fuel and oxidant composition, fuel and oxidant flow ration, utilization and current. The approach is based on findings and evidence obtained in the Molten Carbonate Fuel Cell (MCFC) test programme carried out in the Netherlands by the Netherlands Energy Research Foundation (ECN). 6 figs., 1 ref.
