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.

Abstract
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.Pubblicazioni consigliate
