Design of a test bench for low power PEMFC

摘要

This paper describes a test bench for a fuel cell stack able to provide up to 500We. The architecture of the system(stack, air providing circuit, hydrogen providing circuit, water coolant circuit) and its instrumentation (fluid temperatures pressures and flows, cell voltages, current ...) are described . Three objectives are carried on : full life and property safety running of the electrochemical generator, better understanding of the stack behaviour and the auxiliaries systems, experimental validation of simulations.
