An electric apparatus (air pump), which operates by receiving a power supply from a drive control apparatus (PDU) mounted in a fuel cell vehicle, includes a first connection terminal section configured to directly connect to the drive control apparatus, and a second connection terminal section configured to connect to the drive control apparatus via a cable.

Electric apparatus and electric apparatus module

A fuel cell vehicle includes a fuel cell system and an exhaust gas pipe. The fuel cell system includes a fuel cell stack, an oxygen-containing gas supply line, an oxygen-containing gas discharge line, and an air pump. The air pump includes a compressor provided in an oxygen-containing gas supply line, and an expander provided in an oxygen-containing gas discharge line. An air cleaner is provided upstream of the compressor. An exhaust gas pipe is connected to an expander. The air compressor is closer to the air cleaner than the expander is.

Fuel cell vehicle

The on-off valve includes a body having a fluid path, a spherical valve body opening and closing the fluid path, a guide member opposing the valve body and having a flange portion radially extending outward, a first seat member slidable along an outer peripheral surface of the guide member and seating the valve body, an O-ring disposed between the first seat member and the guide member, a chamber formed of an inner wall portion of the fluid path, the outer peripheral surface, the flange portion, and the first seat member, and a spring member disposed in the chamber and urging the first seat member toward the valve body. In the on-off valve, a gap portion is formed between the inner wall portion and the first seat member and connects the valve body side of the fluid path to the chamber.

Valve device

A method for warming up a fuel cell system comprising; a fuel cell which generates electric current due to an electrochemical reaction between hydrogen and oxygen, and which supplies the electric current to a load, an air supply pipe for supplying air to the fuel cell as an oxidant gas, an air exhaust pipe for discharging exhaust air from the fuel cell to an atmosphere, a compressor provided on either of air supply pipe and air exhaust pipe, which carries the air and a communication pipe which returns exhaust air to air supply pipe, and which communicates exhaust air pipe with air supply pipe to form a circulation cycle including compressor. The method of the present invention comprises: detecting a temperature of the fuel cell, and if the temperature of the fuel cell is lower than a first prescribed temperature, heating fuel cell by circulating the air, which has been heated by a heat generated due to adiabatic compression through compressor prior to supplying the electric current to the load from the fuel cell.

Method and apparatus for warming-up fuel cell and fuel cell vehicle

A gas-supplying apparatus in a fuel cell comprises a compressor which sucks a supply gas to be supplied to a fuel cell from downstream of said fuel cell, and which compresses an exhaust gas, generated from said supply gas by power generation in the fuel cell, exhausted from the fuel cell, and a heat exchanger which performs heat exchange between said supply gas and said exhaust gas. The apparatus has a simple configuration and improved heat efficiency.

Gas-supplying apparatus, gas-supplying mechanism and gas-supplying process in fuel cell

A fuel cell automobile is provided with a fuel cell and an integral module including a drive module, a compression module, and an intercooler. At least one portion of the integral module is mounted to a body of the automobile by way of a mount. Further, a compressed air cooled using the intercooler is supplied to the fuel cell by way of a pipe at least portion of which is made of a resilient member.

Fuel cell automobile capable of reducing vibration

An apparatus for warming-up a fuel cell has means for returning an exhaust gas which returns the exhaust gas to the supply gas depending upon the warning-up conditions of the fuel cell at the time when the supply gas is supplied into the fuel cell and it is discharged as the exhaust gas after utilizing the supply gas in the fuel cell.
