Abstract

This invention relates to an air transportation device for fuel cell engines operating under normal pressure including a motor and an air drum, in which, said motor is set at one side of the air drum and the rotation shaft is vertical to the drum set with an inlet scoop, an oulet scoop and at least an installation hole set at the end of the other side of the drum and axially to the drum or mounted at the end of the motor and set axially to the motor.

Description

technical field [0001] The invention relates to a fuel cell, in particular to an air conveying device for a fuel cell engine operated under normal pressure. 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....
