Abstract: Provided is a valve unit including a first gas flow channel to a gas tank and a second gas flow channel branching off from the first gas flow channel and leading to a gas-consuming device. The valve unit can avoid the entrance of water, which may be included in gas, into the second gas flow channel. The first gas flow channel to let gas from the outside in has a bend. The first gas flow channel has a communication port to the gas tank at an end downstream of the bend. A second gas flow channel branches off at a branching part between the bend and the communication port, and the second gas flow channel leads to the gas-consuming device. A straightening member is disposed between the bend and the branching part, and is to straighten the gas flow from the upstream to be parallel to the direction of the first gas flow channel.

Abstract: A shutoff valve, a first gas pressure sensor, a pressure reducing valve, a second gas pressure sensor, and a gas supply component are provided, sequentially from a gas tank side, in a gas supply flow channel that extends from the gas tank to a gas consuming component. Besides, a buffer tank is provided, via an on-off valve, in a branch flow channel that branches off from the gas supply flow channel between the pressure reducing valve and the gas supply component. This buffer tank is in a situation where the pressure of the buffer tank is not higher than a consumption prescribed gas pressure. In calibrating the first gas pressure sensor, with the shutoff valve closed and with the on-off valve open, a detection value of the first gas pressure sensor is calibrated through the use of a detection value of the second gas pressure sensor.

Abstract: A tank-type power generation device capable of manufacturing high-pressure hydrogen installed in a fuel cell vehicle, which utilizes the hydrogen in order to generate power and can reduce the manufacturing cost of the vehicle without need for a separate fuel cell, and a fuel cell vehicle. A partition member partitions the interior of a tank main body into two sections, and includes a solid polymer electrolyte membrane in contact with the individual sections. A supply means can switch water and a gas containing oxygen to supply it to one section. An electrolytic power generation means includes electrodes on both membrane surfaces and when the water is supplied by the supply means, it can perform electrolysis by applying a voltage between the electrodes to store hydrogen gas in one section and when the gas containing oxygen is supplied, it can generate power by reacting the gas with the hydrogen gas.

Abstract: A fuel cell system employs a fuel cell stack having an air electrode, an electrolyte membrane, and a fuel electrode. The fuel cell system includes an air residual space, from which air supplied to the air electrode is not discharged to stay behind therein when the fuel cell system is stopped. The air residual space communicates with the air electrode. The fuel cell system includes a hydrogen residual space, from which hydrogen supplied to the fuel electrode is not discharged to stay behind therein when the fuel cell system is stopped. The hydrogen residual space communicates with the fuel electrode. A residual ratio satisfies a specific reference range and corresponds to a ratio of the molecular number of hydrogen that stays behind in the hydrogen residual space to the molecular number of oxygen in air that stays behind in the air residual space when the fuel cell system is stopped.

Abstract: A fuel cell system includes a fuel cell, auxiliary devices, an auxiliary device controller, a secondary battery, a current sensor, a voltage sensor, and a diagnosis controller. In an output stop state where the fuel cell does not output electric power, the auxiliary device controller performs a residual water scavenging process of scavenging water remaining in the fuel cell to outside of the fuel cell system by driving the auxiliary devices using electric power supplied from the secondary battery and supplying the gas to the fuel cell. The diagnosis controller diagnoses the secondary battery using a current integrated value that is obtained by integrating amounts of current supplied from the secondary battery in a predetermined voltage range of a discharge voltage of the secondary battery that changes in response to discharge when electric power is supplied to the auxiliary devices by performing the residual water scavenging process.
