Cooling system of hydrogen fuel cell stack

Abstract

The invention discloses a cooling system of a hydrogen fuel cell stack. The left side of a water pump is fixedly connected with the right side of a cooling box through a fixing device, an inner cavityof the cooling box is fixedly connected with an inclined plate and a fixing plate, the output end of the water pump is communicated with a water inlet pipe, the left end of the water inlet pipe penetrates through the right side of the cooling box and extends to the inner cavity of the cooling box, and the right side of the fixing plate is fixedly connected with an air pump. The invention relatesto the technical field of hydrogen fuel cells. According to the cooling system of the hydrogen fuel cell stack, the water flow enters into the water cooling box through the water inlet pipe and then moves leftwards and rightwards through the inclined plate; air is conveyed into an air outlet pipe by an air conveying pipe, the air is uniformly exhausted through a plurality of exhaust grooves uniformly formed in the side surface of the air outlet pipe, the water flow passes through an iron gauze and then moves downwards, the air moves upwards, it is guaranteed that the air makes full contact with the water flow, the air is cooled, the cooled air is used for cooling, the efficiency is guaranteed, and the problems that a common cooling system is low in cooling efficiency and poor in using effect are solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a cooling system for hydrogen fuel cell stacks. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. [0003] When the hydrogen fuel cell is working, it will generate a lot of heat, which needs to be cooled down. However, the fuel cell stack of the hydrogen fuel cell has a narrow working temperature range, so the requirements for the cooling system are relatively high, but the cooling efficiency of the common cooling system is low. , and the working mode is rela...
