Voltage, about 0.7V, so fuel cell is mostly manufactured in a manner of series winding or one group, to increase voltage, fit applications demand.
Existing fuel cell pile assemble when, adopt be screwed, bandage is tied up, rivet, bonding agent packaged type.
After fuel cell long-time use, sealing strip or sealant and membrane electrode (MEA) can inevitably generate aging deformation,
Size reduction is generated in pile longitudinal direction.Aforesaid way is rigid preload, can not adjust compression distance, and pile pre-tightens at this time
Power will reduce, and pile sealing effect is caused to be gradually reduced, and power generation performance reduces, and fuel cells fail is caused even to cause gas
Leakage generates dangerous.
Screw is fixed, bandage is tied up, rivet connection type, in the case of a shock, is also easy to produce loosening, is caused to pre-tighten
Power decline, causes pile sealing effect to decline.
When being sealed using bonding agent, the small molecule that often will cause in poorly sealed or bonding agent reaches combustion with fuel
The surface for expecting cell catalyst, causes battery failure.
