Fuel cell comprising a bipolar module capable of generating heat

Abstract

A fuel cell comprising alternating bipolar modules and membrane-electrode assemblies so as to form a stack comprising at least one electrochemical cell. Each bipolar module comprising at least a first main channel for the circulation of an oxidising fluid, a second main channel for the circulation of a reducing fluid and a third main channel for the circulation of a heat-transfer fluid. The fuel cell comprises at least one heating module, comprising at least one auxiliary channel comprising a catalyst chemical element, the auxiliary channel being configured to circulate a mixture of oxidising fluid and reducing fluid so as to generate heat upon reaction of the oxidising fluid, the reducing fluid and the catalyst chemical element. The auxiliary channel is formed by positioning a spacer plate between two plates.
