Fuel cell for use in motor vehicle, has case defining access opening to access stacked cells in interior volume and defining two auxiliary openings to circulate gas, where external layer is applied on interior volume

摘要

The fuel cell has stacked cells (26), and a case (18) that delimits an interior volume (46) that receives the stacked cells. The case defines an access opening (52) to access the stacked cells in the interior volume, where an external layer (50) is applied on the interior volume. The case defines two auxiliary openings (56, 58) to circulate a gas, where each auxiliary opening is adapted to create the circulation of gas between the access opening and the auxiliary openings to scavenge the stacked cells in the interior volume.
