Fuel cell system for fuel cell vehicle i.e. omni bus, has fuel cell and system components that are enclosed by system housing, and cooling heat exchanger, where air flow passing through system housing is produced by air conveying device

摘要

The system (2) has a fuel cell (5) and system components e.g. humidifier (9), water separator (10), compressor (11), expansion device (12), recirculation conveying device (16) and valve device (18), that are enclosed by a system housing (19), where air flow passing through the system housing is produced by an air conveying device (27). The air flow is passed through a heat exchanger (26) before entering into the system housing, where the heat exchanger is designed in an electrically heated manner. A cooling heat exchanger (8) is arranged in an area of the fuel cell. Independent claims are also included for the following: (1) a fuel cell vehicle (2) a method for preparation of starting of a fuel cell system.
