A cooling system for a hydrogen fuel cell stack

Abstract

The invention discloses a cooling system for a hydrogen fuel cell stack. The left side of the water pump is fixedly connected to the right side of the cooling box through a fixing device. The inner cavity of the cooling box is fixedly connected with a sloping plate and a fixing plate, and the output end of the water pump is connected to the cooling box. There is a water inlet pipe. The left end of the water inlet pipe runs through the right side of the cooling box and extends to the inner cavity of the cooling box. An air pump is fixedly connected to the right side of the fixing plate. The invention relates to the technical field of hydrogen fuel cells. In the cooling system of the hydrogen fuel cell stack, the water flows through the water inlet pipe into the water cooling box, and then moves downward through the inclined plate, and the air delivery pipe transports the air into and out of the air pipe, and discharges it evenly through multiple exhaust slots evenly opened on the side of the air outlet pipe. The water flow moves downward after passing through the barbed wire, and the air moves upward to ensure that the air is in full contact with the water flow, and the air is cooled, and the cooled air is cooled to ensure efficiency, which solves the problem of low cooling efficiency and ineffective use of common cooling systems. good question.

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...
