    Abstract: A fuel cell assembly includes a first bipolar plate, a second bipolar plate, and a diffusion-electrode assembly. A first top surface of the first plate includes a first seal protruding upwardly and a first raised feed channel adjacent the first seal and protruding upwardly. A second bottom surface of the second plate includes a second seal protruding downwardly and a second raised feed channel adjacent the second seal and protruding downwardly. The diffusion-electrode assembly includes a membrane layer having a membrane frame extending therefrom and two gas diffusion layers. The first and second plates are arranged parallel, the first and second seals align with each other, and the first and second raised feed channels align with each other. The first and second raised feed channels contact the membrane frame arranged therebetween so as to prevent mechanical deformations of the first and second plates.

    Abstract: A fuel cell module is configured or operated, or both, such that after a shut down procedure a fuel cell stack is discharged and has its cathode electrodes at least partially blanketed with nitrogen during at least some periods of time. If the fuel cell module is restarted in this condition, electrochemical reactions are limited and do not quickly re-charge the fuel cell stack. To decrease start up time, air is moved into the cathode electrodes before the stack is re-charged. The air may be provided by a pump, fan or blower driven by a battery or by the flow or pressure of stored hydrogen. For example, an additional fan or an operating blower may be driven by a battery until the fuel cell stack is able to supply sufficient current to drive the operating blower for normal operation.

    Abstract: A process for starting a PEM fuel cell module includes blowing air through the cathode side of the module using external power. An amount hydrogen is released into the anode side of the module under a pressure greater than the pressure of the air on the cathode side, while the anode is otherwise closed. Cell voltages in the module are monitored for the appearance of a charged state sufficient to start the module. When the charged state is observed, the module is converted to a running state.

    CPC classification number: H01M8/0258

    Abstract: An electrochemical cell has first and second flow fields on opposite sides of a membrane. The first flow field has a set of generally linear channels in which the flow of a fluid in the field is contained between parallel elongate ridges. The second flow field is defined by a set of parallel discontinuous ridges. Preferably most ridge segments in the second flow field are oblique, for example perpendicular, to and overlap with two or more ridges of the first flow field. The flow fields may be used in, for example, water electrolysis cells including high or differential pressure polymer electrolyte membrane (PEM) electrolysis cells.

    Abstract: An electrolyser operates within an energy system, for example to provide grid services, energy storage or fuel, or to produce hydrogen from electricity produced from renewable resources. The electrolyser may be configured to operate at frequently or quickly varying rates of electricity consumption or to operate at a specified power consumption. In one process of operating an electrolyser, a series of dispatches is received indicating a specified power consumption for a period of time. The dispatches may occur at least once every 30 minutes. The electrolyser is operated according to the dispatches. Hydrogen produced by the electrolyser is discharged to a natural gas system.
