Normal pressure air suction type operation and cooling fuel cell

Abstract

The related normal-air suction fuel cell comprises: two cell modules shared one front and back end, a set of air supply device on module top, and a set of hydrogen supply device connected with hydrogen inlet and outlet on module ends. Wherein, the air exhaust ends of two modules are set oppositely to form a channel. Compared with prior art, this invention is low cost and compact, and needs less power consumption.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a normal-pressure air suction type operation and cooling fuel cell. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a current loop.
