摘要： A flow field plate for a fuel cell that has one or more outer layers that makes the plate more conductive and hydrophilic. In one embodiment, the coating is co-deposited as combination of a conductive material and a metal oxide coating. A suitable conductive material is gold and suitable metal oxides include SiO2, HfO2, ZrO2, Al2O3, SnO2, Ta2O5, Nb2O5, MoO2, IrO2, RuO2 and mixtures thereof. The conductive material and metal oxide can also be deposited as two separate layers, where the metal oxide is the outer layer. According to another embodiment, a metal layer is deposited on the plate with nanopores that provide the hydrophilicity. Also, doping ions can be added to the metal oxide to provide low fluoride solubility of the coating to control the rate that hydrofluoric acid etches away the oxide layer.

摘要： The invention describes a bipolar unit consisting of a pair of metal plates at least one of which is corrugated, fixed by continuous and hydraulically impervious connections, and provided on the external surfaces thereof with porous electric current collectors also suitable for the distribution of the gaseous reactants. The collector facing the plate corrugations is interpenetrated therein, thereby achieving a continuous contact. Two bipolar units of the invention and one interposed MEA element are assembled to form an elementary fuel cell with an improved electric current distribution. Furthermore the channels formed between the mutually contacting surfaces of the plate pair by the corrugations of at least one of the plates of each bipolar unit, are crossed by a coolant allowing to optimally adjust the cell operative temperature.

摘要： A conductive and tabular separator is inserted into the gap between the fuel electrode layer of an i-th power generating cell and the oxidizer electrode layer of an (i+1)-th power generating cell adjacent to the fuel electrode layer. A fuel supply passage is so formed on one face of each of these separators that a fuel gas flows radially from almost the center of the fuel electrode layer to its edge. An oxidizer supply passage is so formed on the other face that an oxidizer gas outgoes almost uniformly in a shower toward the oxidizer polar layer. Thus, all of the surfaces of the power generating cells contribute to power generation to increase the frequency of collision between the fuel gas and the fuel electrode layer and that between the oxidizer gas and the oxidizer electrode layer, and to improve the generation efficiency.
