摘要： Proposed is a fuel cell power control system. A fuel cell generates electric power. A load unit is electrically connected to the fuel cell. A DC/DC converter is disposed between the fuel cell and the load unit to convert the electric power between a low side of the DC/DC converter electrically connected to the fuel cell and a high side of the DC/DC converter electrically connected to the load unit. A battery is electrically connected to the high side of the DC/DC converter to be parallel to the load unit. A controller monitors a voltage of the load unit, the battery, or the high side of the DC/DC converter, and controls the electric power input to the load unit or output from the load unit in accordance with the monitored voltage.

摘要： A method is for operating a commercial vehicle having a fuel cell system and an electromotive drive. The method includes: supplying reactants to a fuel cell of the fuel cell system, wherein the fuel cell is adapted to be operated at a changeable working point, activation of the fuel cell such that, via reaction of the supplied reactants, electrical energy is generated at a generated power, intermediate storage of the generated electrical energy at the corresponding power in a buffer store, and driving of the electromotive drive by withdrawal of electrical energy from the buffer store at a corresponding power. The method can further include: determination of weight information that is representative of the load state of the commercial vehicle, and adaptation of the working point in dependence on the determined weight information.

摘要： A method for operating a fuel cell system includes drawing a base level DC electric energy from a first fuel cell of a first type to a combined DC bus, measuring a DC voltage at the combined DC bus, determining whether the DC voltage at the combined DC bus falls short of a DC voltage threshold, and drawing a variable DC electric energy from a second fuel cell of a second type different from the first type in response to determining that the DC voltage at the combined DC bus falls short of the DC voltage threshold.

摘要： An electrochemical hydrogen compression system includes a hydrogen compression stack, and a control device. The control device is equipped with an operation control unit that causes hydrogen gas to be supplied to a hydrogen compression stack, together with causing an electrical current to be supplied to the hydrogen compression stack from an electrical power source device, and causes a compression operation to be executed by the hydrogen compression stack, and an operation stop control unit which, upon receiving an operation stop command during execution of the compression operation, causes the liquid water to be supplied to the hydrogen compression stack, and thereafter causes the hydrogen gas to be supplied to the hydrogen compression stack.

摘要： A fuel cell system includes: a steam generator configured to heat water to generate steam; a reforming part configured to cause a reaction between the steam and hydrocarbon to generate a reformed gas containing hydrogen; a fuel cell stack, which has an anode and a cathode, and is configured to generate electric energy through an electrochemical reaction caused between the reformed gas supplied to the anode and an oxidant supplied to the cathode; and an ejector configured to supply at least one of a raw material containing the hydrocarbon or an anode circulating gas obtained by recovering a part of an anode exhaust gas discharged from the anode to the reforming part by using the steam as a driving fluid. The steam generator includes: an evaporation flow passage through which the water flows; an anode exhaust gas flow passage that is thermally connected to the evaporation flow passage and through which the anode exhaust gas flows; and an auxiliary heating device configured to heat the water. The anode exhaust gas flow passage and the auxiliary heating device are opposed to each other across the evaporation flow passage.

摘要： 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.
