Abstract
The present invention is a hydrogen exhaust device for fuel cell. A tail gas discharge device for a fuel cell system includes a steam trap, a buffer solenoid valve, a buffer tank and a drain solenoid valve. The steam trap can collect water from wet hydrogen. The buffer tank is a hollow cavity structure such as a tank. Preferably, the steam trap has an upper cover, a main body, a lower cover and a filter. The upper cover has a wet hydrogen inlet, a pressure sensor, a dry hydrogen outlet and a temperature sensor. The lower cover has a liquid storage cavity and a filter support part. The filter has a filter filler and a filter intake channel.
