Abstract: Provided are a fuel cell system and a vehicle that can improve the power recovery efficiency in a supercharger of a fuel cell vehicle. A fuel cell system according to an aspect of the present disclosure includes: a fuel cell; a supercharger configured to increase a pressure of intake air of the fuel cell by rotating a turbine with an exhaust of the fuel cell; and a heat pump apparatus configured to absorb heat from a predetermined heat source to increase a temperature of the exhaust supplied to the turbine.

Abstract: A fluid control valve is connected to a wet gas flow passage in order to control a flow of a wet gas, and includes an introduction passage for introducing the wet gas into the fluid control valve, a filter including mesh for removing foreign matter contained in the wet gas flowing through the introduction passage, a discharge passage that includes a valve port disposed above the introduction passage and discharges the wet gas that has passed through the filter from the fluid control valve through the valve port, and a valve portion that opens and closes the valve port using a valve body. In this fluid control valve, the filter is disposed in a lowermost portion of the introduction passage.

Abstract: [Problem] The object of the invention is to provide the filter device disposed in the moist fluid passage of the fuel cell system in that, water is not adhered and never remains in the filter and when leaving it under the low temperature after the system stops, blockage by freezing the filter can surely be prevented, and the complex control and the heat source such as heaters for the decompression as conventional is unnecessary, and the filter device is cheap and compact.

Abstract: A fuel cell stack includes a heat exchange unit that performs heat exchange between a gas mixture containing source hydrogen and a circulating gas and cooling water used for controlling the temperature of the fuel cell stack. A system controller adjusts the temperature of the cooling water by controlling a temperature control unit on the basis of the temperature of source hydrogen flowing into a junction at which the source hydrogen and a circulating gas are mixed such that the temperature of a source/recirculated hydrogen mixture that is mixed at the junction and that is supplied to the fuel cell stack is kept within a managed temperature range.

Abstract: A pressure vessel structure includes a vessel main body, and a grid layer provided on a periphery of the vessel main body and including a plurality of grid lines formed by intersecting strip-form raw materials so as to overlap alternately. Thus, a burst pressure of the pressure vessel is increased.

Abstract: A fuel gas supply device for supplying fuel gas to a fuel cell stack includes a control valve provided in a fuel gas path connecting a fuel tank and the fuel cell stack, an upstream-side pressure sensor and a downstream-side pressure sensor for detecting an upstream-side pressure and a downstream-side pressure, and a programmable controller. The programmable controller calculates a required opening based on a target fuel gas pressure and the downstream-side pressure and calculates an opening time and a closing time based on the required opening and the upstream-side pressure, or calculates an opening time and a closing time based on the target fuel gas pressure and the downstream-side pressure and calculates a required opening based on the opening time and the upstream-side pressure, and controls the control valve using the calculated required opening, opening time and closing time.

Abstract: A fuel cell system having a fuel cell for causing reactant gas to be electrochemically reacted to generate power, a reactant gas supply path for supplying reactant gas to the fuel cell, a reactant gas recirculation path for recirculating exhaust gas discharged from the fuel cell and combining the recirculating exhaust gas with reactant gas flowing through the reactant gas supply path to the fuel cell, and a pump unit disposed in the reactant gas recirculation path to pump the recirculating exhaust gas through the reactant gas recirculation path. A pump-tempering apparatus increases the temperature of the pump unit and a controller controls the pump-tempering apparatus. After the controller receives a fuel cell system stop signal, the controller controls the pump-tempering apparatus such that the temperature of the pump unit becomes higher than the temperature of piping in the reactant gas recirculation path.
