Abstract

The invention discloses a fuel cell hydrogen circulation device and a fuel cell applied thereby. The device comprises a tank body, a tank cover, a galvanic pile module, a hydrogen circulation device,an air gas path system, a cooling system, a ventilation component and a hydrogen inlet integrated clamping block, wherein the hydrogen circulation device comprises a hydrogen circulation pump equippedwith a heater and a temperature sensor. The temperature of the hydrogen circulation device is detected by a temperature sensor, and the hydrogen circulation device is heated by a heater at an appropriate time to realize a cold start function.

Description

Technical field: [0001] The invention relates to a fuel cell hydrogen circulation device and a fuel cell applied thereto. Background technique: [0002] Existing hydrogen energy fuel cells generally include a box body, a box cover, a stack module (that is, a fuel cell stack—that is, a plurality of independent single fuel cells connected in series), a fuel cell hydrogen inlet adjustment assembly, and a stack gas outlet. Valve group, fuel cell hydrogen circulation device, air gas system and cooling system, in which the stack module, fuel cell hydrogen inlet adjustment assembly, and stack gas outlet valve group are all installed in the air gas system, cooling system, The hydrogen circulation pump is installed outside the box. [0003] The fuel cell hydrogen circulation device is used to directly pump the unreacted hydrogen on the hydrogen circuit from the anode side outlet of the fuel cell stack back to the anode side inlet, merge with the freshly injected reactant gas at the ...
