FUEL CELL PROVIDED WITH A TEMPERATURE-CONTROL SYSTEM AND METHOD FOR THERMAL CONTROL OF THE CELL

摘要

The invention relates to a fuel cell (10) which comprises a membrane/electrode assembly (16) and two gas-diffusion layers (14), forming an elementary cell (12) with the assembly. The cell (10) also includes a two-phase heat sink (24) comprising a condensation area and an evaporation area, the evaporation area being arranged between the bipolar plates (14) of two adjacent elementary cells (12). The two-phase heat sink (24) also comprises a heating element arranged in the condensation area. The invention also relates to a system which includes the fuel cell and a controller as well as a method for thermal control of the fuel cell.
