Abstract: A control unit is configured to communicate with a terminal owned by a power company. When a hydrogen generation request is received from the terminal, the control unit determines whether hydrogen is to be generated based on a state of a hydrogen generation device, and transmits a determination result to the terminal. When a power sale request is received from the terminal, the control unit determines whether power is to be sold based on a state of the hydrogen generation device, and transmits a determination result to the terminal.

Abstract: A method for operating a fuel cell power plant is provided to deliver power and/or receive power from a load. The fuel cell power plant includes an energy storage system connected in parallel with a fuel cell system. The method for operating includes the steps of calculating and actively proportioning a current split between the fuel cell system and the energy storage system, and controlling the proportioning using fuel cell system air flow. In one embodiment, set point changes in the fuel cell system air flow are operationally independent from a fuel cell water management system that removes product water, humidifies inlet reactant gas, and/or cools the fuel cell stack. In another embodiment, the step of calculating the current split proportion includes the selection of points on a family of V/I curves within a range from 40% fuel cell air utilization to 99% fuel cell air utilization.

Abstract: A bipolar plate assembly for a fuel cell includes a first bipolar sheet having elongated lands formed thereon each defining secondary channels therein. The first bipolar sheet further includes primary channels formed between adjacent elongated lands. The first bipolar sheet includes an active area at which fluids flowing through the primary and secondary channels electrochemically react with an adjacent gas diffusion layer of the fuel cell. Top surfaces of the elongated lands include injectors formed as a hole in the top surfaces and located in the active area of the first bipolar sheet. Fluid flowing through the secondary channels is forced through the injectors, subsequently into the adjacent gas diffusion layer, and subsequently into and adjacent primary channel.
