| 摘要 |
This invention provides a compact safety type fuel cell system, including an enclosure and the electronic control system, electric isolation board, gas isolation board, fuel cell stack system, hydrogen delivery device installed in the enclosure. The electric isolation board divides the inside of the enclosure into electronic control system space and fuel cell stack working space, the gas isolation board divides the fuel cell stack working space into hydrogen side space and air inlet space, the air inlet space and the air inlet port of the fuel cell stack system are connected, the fuel cell stack system enclosure connects with the gas isolation board hermetically. This invention achieves electric isolation in a limited space and the effective isolation between air and hydrogen, which can directly replace the lead-acid cell system on battery-powered forklift being widely used now, requires no forklift redesign due to such problems as insufficient placing space, etc. and facilitates upgrading. |
