CA 2597796

According to the invention, a fuel cell is operated at a working temperature of between 60 ~C and 110 ~C and thermally insulated from the exterior, the waste air from the cathode being cooled by a surplus of incoming air that is provided for the reaction. The supplied fuel is pre-heated during the exchange of heat. The fuel cell that is operated according to said method can be used in systems that are restricted by exposure to thermal stress and can be produced in a cost-effective manner.

Afin d'obtenir une puissance élevée, une pile à combustible est utilisée à une température de travail située entre 60 °C et 110 °C et présente une isolation thermique vers l'extérieur, alors que l'air d'évacuation de cathode est refroidi avec un excédent d'air d'alimentation préparé pour la réaction. Le combustible d'alimentation est préchauffé dans le cadre d'un échange thermique. La pile à combustible ainsi utilisée peut être intégrée dans des systèmes à charge thermique limitée et il est possible de la fabriquer de manière économique.
