Description
Technical field
The invention belongs to fuel cell fields, and present invention relates particularly to a kind of fuel cell hydrogen reflow methods.
Background technique
The effect of hydrogen reflux pump is that unreacting hydrogen is gone out from fuel cell on fuel cell electricity-generating system hydrogen circuit
Mouth directly blowback fuel cell inlet, enters fuel cell after converging with entrance reaction gas.It on the one hand can be real using reflux pump
The moisture content of reaction tail-gas is now brought into battery and plays humidification；On the other hand, hydrogen can be improved in anode of fuel cell
Flow velocity in runner prevents the accumulation of anode water, avoids anode water logging；The purpose for improving hydrogen utilization ratio is also played simultaneously.
