摘要： A bipolar plate (30) for use in a fuel cell stack (10) includes one or more first metal layers (40a) having a tendency to grow an electrically passive layer in the presence of a fuel cell reactant gas and one or more second metal layers (40b) directly adjacent the one or more first metal layers (40a). The second metal layer has a tendency to resist growing any oxide layer in the presence of the fuel cell reactant gas to maintain a threshold electrical conductivity. The second metal layer also has a section for contacting an electrode (12, 14) and providing an electrically conductive path between the electrode (12, 14) and the first metal layer.

摘要： The invention is a method of using a temporary dilute surfactant water solution to enhance mass transport in a fuel cell (10) that generates electrical current from hydrogen containing reducing fluid and oxygen containing oxidant reactant streams. The method includes the steps of: a. directing the dilute surfactant water solution to flow through a cathode flow field (20) of a fuel cell (10); b. then removing the solution from the fuel cell (10); and, c. then directing flow of the reactant streams through the flow fields (12) (20). The temporary dilute surfactant water solution has a surface tension of not less than 50 dynes/cm. Flowing the temporary dilute surfactant water solution through the fuel cell (10) for a temporary, short duration improves mass transport of the cell (10) even after the solution is removed from the cell (10).

摘要： A fuel cell system having a stack of proton exchange membrane fuel cells is operated in sub-freezing temperatures by draining any liquid water from the fuel cell water flow passages upon or after the previous shut-down of the stack before freezing can occur, and, thereafter a) starting-up the stack by directing fuel and oxidant reactants into the cell and connecting a load to the stack; b) using heat produced by the stack to increase the operating temperature of the stack to melt ice within the stack; and, c) upon the stack operating temperature reaching at least 0° C., circulating anti-freeze through stack coolers to maintain the temperature of the stack low enough to maintain a sufficiently low water vapor pressure within the cells to prevent cell dry out for at least as long as there is insufficient liquid water to circulate through the water flow passages.

摘要： Recovery of PEM fuel cell performance is achieved by evacuating (61, 62) or by flowing water absorbing gas (46) through, or both, the fuel flow field (12, 13, 19, 20), the air flow field (25, 26, 30, 31), and the water flow field (36, 39), while resistance of the individual cells, or of the fuel cell stack, is measured; the dry out process is continued until the resistance of the cells (or the resistance per cell, measured across the fuel cell stack as a whole), has increased by at least 5 to 1 (preferably 10 to 1) over the normal resistance of the cells. The water absorbing gas may be air (23) or nitrogen (47); it may be at ambient temperature or heated (50).
