Abstract

The related module composite normal-pressure fuel cell device comprises at least two set of modular fuel cell stacks connected in series of parallel. Compared with prior art, this invention has compact structure and large power.

Description

technical field [0001] The present invention relates to a fuel cell, in particular to a module-combined normal-pressure operation fuel cell power generation device. 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 curre...
