Abstract

The invention belongs to the technical field of fuel cells, and discloses a fuel cell stack module and a fluid control method.The fuel cell stack module comprises at least one stack assembly, and the stack assembly comprises two stack sets, a feeding assembly and a discharging assembly which are sequentially stacked in the height direction; the galvanic pile group comprises two single galvanic piles which are sequentially stacked in the height direction, and an inlet group and an outlet group are symmetrically arranged at the two ends of each single galvanic pile in the length direction; the feeding assembly is used for communicating with the inlet group of each single electric pile, the discharging assembly is used for communicating with the outlet group of each single electric pile, and fluid can synchronously flow into the inlet group of each single electric pile through the feeding assembly and synchronously flow into the discharging assembly from the outlet group of each single electric pile. According to the fuel cell stack module, the output performance of each single stack is consistent, so that the output performance of the single stack is effectively improved, and the service life of the fuel cell is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell stack module and a fluid control method. Background technique [0002] A fuel cell is a device that uses an oxidant (air, oxygen, etc.) and a reductant (hydrogen, hydrogen storage materials, etc.) to generate electricity through an electrochemical redox reaction. Existing fuel cells mainly include a fuel cell stack core and auxiliary components. The fuel cell stack core is formed by stacking dozens to hundreds of single cell stacks in series. The core structure of the reaction is the membrane electrode; the auxiliary components are used to compress the fuel cell stack core and provide oxidant, reductant and coolant to the cell stack core for electrochemical redox reaction. [0003] Due to the large number of inlets and outlets of a single cell stack, when multiple cell stacks are integrated into a fuel cell stack core, the multiple inlets and outlets and the manif...
