摘要： A method of starting operation of a fuel cell system which includes at least a fuel cell stack the method includes opening an anode inlet valve to allow fuel to enter an anode volume of the fuel cell stack; then operating an air compressor in fluid communication with a cathode air inlet of the fuel cell stack to allow air to enter a cathode volume of the fuel cell stack monitoring the temperature of the cathode inlet and/or outlet operating a water injection system to inject water into the cathode volume once the temperature of fluid passing through the cathode inlet and/or outlet exceeds a preset level, wherein a current drawn from the fuel cell stack is limited to prevent a voltage measured across one or more cells in the fuel cell stack from falling below a first voltage threshold.

摘要： Methods of manufacturing electrochemical cells having a current collector which, at least in part, underlies a catalyst layer are discussed. A method comprises patterning a current collector to have at least one electrolyte opening, disposing an electrolyte into or through the at least one opening, and disposing a catalyst, at least in part, over the disposed electrolyte. Optionally, the method comprises pattering a substrate and attaching a patterned current collector to each side thereof. Patterning of the current collector can include patterning a continuous sheet, which comprises at least a first and a second separable current collector. In one such example, a continuous carbon-fiber sheet impregnated or laminated with a non-porous material is patterned. In another such example, a continuous plastic material sheet impregnated with one or more electrical conductive particles is patterned. Among other things, the pattern of the current collector can include an extruded slot or adjacently-disposable strips.

摘要： An electrochemical fuel cell includes a membrane-electrode assembly (MEA) having a cathode face and an anode face. The MEA is between a cathode fluid flow field plate and an anode fluid flow field plate. A diffusion structure is between the MEA and a corresponding fluid flow field plate, which is either the cathode fluid flow field plate or the anode fluid flow field plate. The diffusion structure has a first face in contact with, or adjacent to, the MEA and a second face in contact with, or adjacent to, the corresponding fluid flow field plate. The diffusion structure includes a first layer having a first level of hydrophobicity and a second layer that is hydrophilic. The second layer is adjacent to the corresponding fluid flow field plate, and includes a hydrophilic binder material.
