Embodiment

[0033] see Figure 1-4 , the present invention provides a technical solution: a liquid-cooled stacked battery assembly 1, comprising:

[0034] The single cells stacked in series and the cooling zone 105 for entering and exiting the cooling liquid are used for the function of the assembly auxiliary positioning device. The cooling zone 105 is a sealed space with a liquid inlet and outlet. The cooling liquid in the cooling zone 105 is made to flow in one direction.

[0035] The liquid-cooled stacked battery assembly 1 is divided into a fast cooling zone A close to the liquid cooling source and a slow cooling zone B far away from the liquid cooling source; for example figure 2 As shown in the figure, the rectangular plates arranged therein are regarded as single cells, the components embedded between the single cells are the cooling zone 105, and the left side of the liquid-cooled stacked battery assembly 1 (near the liquid cooling source) is the rapid cooling zone A, The right...

Abstract

The invention belongs to the technical field of hydrogen fuel cells, and particularly relates to a liquid-cooled stacked cell assembly and a hydrogen fuel cell stack, and the liquid-cooled stacked cell assembly comprises single cells and a cooling area used for feeding and discharging cooling liquid which are sequentially connected in series and stacked; the liquid-cooled stacked battery assembly is divided into a rapid cooling area A close to a liquid-cooled source and a slow cooling area B far away from the liquid-cooled source; a cooling area is arranged in the rapid cooling area A at an interval of two single batteries; and a cooling area is arranged in the slow cooling area B every other single battery. The hydrogen fuel cell stack comprises an outer shell, the outer shell is hollow and is provided with openings at two ends, the liquid cooling superposed cell assembly is arranged in the outer shell, and the openings at the two ends of the outer shell are closed. The fuel cell disclosed by the invention belongs to a metal plate liquid-cooled galvanic pile, and has the advantages of simple structure, easiness in assembly, high power generation efficiency, small volume, high power density, single cell consistency and the like.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a liquid-cooled stacked battery assembly and a hydrogen fuel cell stack. Background technique [0002] A hydrogen fuel cell is a power generation device that uses hydrogen as fuel to directly convert the chemical energy in the fuel into electrical energy through an electrochemical reaction. It has the advantages of high energy conversion efficiency, zero emissions, and no noise. Actively developing hydrogen energy is an important measure for energy innovation and development to achieve carbon peaking and carbon neutrality. [0003] The stack is composed of multiple single cells stacked together. The stack is the place where the electrochemical reaction occurs, and is the core part of the fuel cell power system. When the stack is working, hydrogen and oxygen are respectively introduced from the inlet, distributed to the bipolar plates of each single cell through the ...
