Abstract
The invention relates to a fuel cell (10) comprising a membrane electrode assembly (16) and two gas diffusion layers (14) co-operating with the assembly to form a unit cell (12). The fuel cell (10) also has a two-phase thermal diffuser (24) having a condensation zone and an evaporation zone, the evaporation zone being arranged between the bipolar plates (14) of two adjacent unit cells (12). The two-phase thermal diffuser (24) also has a heating element arranged in the condensation zone. The invention also provides a system comprising the fuel cell and a controller, and it also provides a method of regulating the temperature of the fuel cell.
