Abstract

A membrane fuel cell stack characterised by a stable operation under non-humidified air feed at the cathode inlet with a stoichiometric factor higher than 1 and near ambient pressure, even at high current density. This result is obtained by means of an air feed conditioning device comprising a fan or little compressor, a heat exchanger directed to cool the compressed air and an expander allowing to cool the air while recovering part of the energy consumed by the fan.
