Abstract

The invention relates to the technical field of fuel cells and in particular relates to a novel cooling water runner plate of a fuel cell stack and a battery pack thereof. The cooling water runner plate comprises a water runner plate body, a hydrogen input overall channel hole and an air input overall channel hole are successively formed in the left side of the water runner plate body, and a hydrogen output overall channel hole and an air output overall channel hole are separately formed in the right side of the water runner plate body and correspond to the hydrogen input overall channel hole and the air input overall channel hole; an inlet parallel runner is formed in the upper portion of the water runner plate body and an outlet parallel runner is formed in the lower portion of the water runner plate body; the inlet parallel runner and the outlet parallel runner separately communicate with a water dividing runner and a water runner in the water runner plate body; and a first dividing cylinder is arranged between the water dividing channel and the water runner. According to the fuel cell cooling water runner and a setting method provided by the invention, residual heat generated in an electrochemical reaction can be more effectively taken away, so that the power generating efficiency of fuel cells is enhanced.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a novel fuel cell stack cooling water channel plate and a battery pack thereof. Background technique [0002] A fuel cell is an electrochemical device that can directly convert the chemical energy stored in fuel into electrical energy through an electrochemical reaction. Proton exchange membrane fuel cell is a low-temperature fuel cell, the working temperature is generally 40-80 ℃, its energy conversion efficiency is high (40%-60%), it is environmentally friendly, it has low noise, fast start-up, no corrosion, preparation Easy and long service life and other advantages. [0003] When the fuel cell is working, hydrogen or other fuel is input to the anode, and the electrochemical reaction of hydrogen or other fuel oxidation and oxygen reduction occurs on the interface between the electrode and the electrolyte, generating current and outputting electrical energy. During the ele...
