CN101243573B 具有完整密封性的燃料电池的双极板和具有该双极板的燃料电池单元 有权

具有完整密封性的燃料电池的双极板和具有该双极板的燃料电池单元
Abstract:
本发明主要涉及一种燃料电池的双极板(22)，该双极板在其至少一个面(51)上包括至少一个凸边(47，23a，33a，40a，27a，35a，41a，23a)，该凸边完全或部分地支持密封垫(54)，以便确保所述电池的在助燃剂进入线路、燃料进入线路、载热流体进入线路、助燃剂输出线路、燃料输出线路和载热流体输出线路中的至少一个流体线路的密封性，其中密封垫是金属薄片或者丝印的，所述线路是由在所述板(22)上分别形成助燃剂和燃料的进入和输出装置(33，40，35，41)的开口和分别形成载热流体进入和输出装置(23，27)的开口的重叠而形成的。
Abstract(English):

The invention relates to a fuel cell bipolar plate (22) comprising at least one ridge (47, 23a, 33a, 40a, 27a, 35a, 41a, 23a) on at least one of the faces (51) thereof, such as seal at least one fluid circuit in the cell from among the oxidant, fuel and coolant inlet circuits and the oxidant, fuel and coolant outlet circuits, said circuits being formed by stacking openings which are provided in the plate (22) and which form an inlet and an outlet for the oxidant and the fuel (33, 40, 35, 41) respectively and openings which form an inlet and an outlet for the coolant (23, 27) respectively during the assembly of the constituent cells (1) of the fuel cell.
