Abstract

The invention provides a proton exchange membrane of a proton exchange membrane fuel cell. A plastic frame is fixedly arranged at four sides of the proton exchange membrane, and partial plastic frameis cemented at four sides of the proton exchange membrane; whereby partial plastic frame covers and is cemented at four sides of the proton exchange membrane to increase the material strength of the proton exchange membrane plate.

Description

technical field [0001] The invention discloses a fuel cell, in particular to a proton exchange membrane structure of a proton exchange membrane fuel cell. Background technique [0002] A fuel cell is a power generation device that directly converts chemical energy in fuel and oxidant into electrical energy through an electrocatalytic reaction on electrodes. The fuel cell is mainly composed of a proton exchange membrane and a bipolar plate. Among them, the proton exchange membrane is the core of the fuel cell and a dense proton selective permeation functional membrane, so it is a key component of the proton exchange membrane fuel cell (PEMFC). One of them plays a role in separating fuel and oxidant and preventing them from reacting directly. At the same time, it also plays the role of conducting protons and insulating electrons, and its performance directly affects the performance, energy conversion efficiency and service life of the fuel cell.
