Abstract
Energy conversion in electrochemical power devices is increasingly cor related with high density waste heat generation, since cell stacks hav e become highly compact. To predict the transient thermal behaviour of fuel cells, a three-dimensional simulation of their stack operation h as been developed. Time constants of the transient response following load changes are determined and are in good agreement with experimenta l data obtained from a 100 W fuel cell stack.
