Abstract

The invention discloses a reaction gas humidifier for a proton exchange membrane fuel cell, comprising a humidification tank, a heating jacket, a thermocouple, a porous metal material, an inlet air pipe, an outlet air pipe, purified water, a temperature controller, a gas flow controller and the like. The humidifier can control the reaction gas humidification of the fuel cell accurately, has the advantages of adjustable humidification amount, ideal humidification effect, no liquid water drops, high humidification speed, simple and practicable device, lower cost and the like, and can be suitable for a test experiment system of the proton exchange membrane fuel cell.

Description

technical field [0001] The invention relates to a humidifier, in particular to a reaction gas humidifier for a proton exchange membrane fuel cell. Background technique [0002] A fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy through electrochemical reactions. The difference between the fuel cell and the general power generation device is that the chemical energy stored in the fuel and the oxidant can be directly converted into electrical energy through the electrochemical reaction, the energy conversion efficiency is high, the environment is not polluted, and it has broad development prospects. Proton exchange membrane fuel cell (PEMFC) is a new, efficient and clean fuel cell. Its power generation efficiency can reach about 60%. [0003] The main components of proton exchange membrane fuel cell (PEMFC) are membrane electrode assembly (MEA), bipolar plate and gas diffusion layer. There are ma...
