Abstract：
 The portable power supply includes through binding bolt cascaded energy unit of hydrogen fuel set and power unit of fuel cell pile composed of bipolar plate, membrane electrode, fuel fluid field plate, air flow field plate, afflux plate, end plate and gasket. Annular bipolar plate having grooves for distributing gas on two sides instead of metal separate board is adopted in the invention. Eliminating complicated drain tap and simplified fastener ingrates unit of source of hydrogen and fuel cell pile in type of self-respiration. Features are: favorable air-tightness, lowered cost, weight, and cost. It is a convenient portable electrical source: no need have charged from AC, self-respiration without manual intervention.
