Fuel cell system for use in motor vehicle, has compressor driven by high pressure of primary fuel and/or hydrogen, where primary hydrogen flows via pressure-reduction valve into compressor

摘要

The system has a compressor (11) driven by a high pressure of a primary fuel and/or hydrogen (10). The primary hydrogen flows via a pressure-regulator valve (12) into the compressor. The compressor is located downstream from a pressure regulator which reduces the pressure of hydrogen. A bypass between the pressure regulator and the hydrogen metering device has a variable throttle to supply the hydrogen to a fuel cell.
