High Temperature PEM (HT PEM) fuel cell based on
polybenzimidazole (PBI) polymer and phosphoric acid, can be
operated at temperature between 120° C and 180 °C.
Reactants humidification is not required and CO content up to
1% in fuel can be tolerated, affecting only marginally
performance. This is what makes HT PEM fuel cells very
attractive, as low quality reformed hydrogen can be used and
water management problems are avoided. Most of published
research on HT PEM fuel cells focuses on membrane issues,
while fuel cell architecture and test protocols are topics not
often mentioned. The aim of this paper is to analyze the
performance of a HT PEM fuel cell operating under different
operating conditions and with different types of fuels.
