Rotary proton exchange film fuel battery

Abstract

The invention discloses a proton exchange membrane flue cell of rotating disk type, which comprises a rotating disk that can rotate around a centre axle vertical to the surface of the disk; the rotating disk comprises a disk rack 4 with certain thickness and a fixing device 5 arranged on the disk rack used for fixing a proton exchange membrane 2 that is clamped and overlapped by anode parts 3 and cathode parts 1, and the surface of the external wall of the rotating disk is formed by the cathode parts, and the surface of side wall of the internal chamber of the rotating disk is formed by the anode parts. The chamber and the outer side of the rotating disk in cathode reaction atmosphere are sealed and separated; the chamber of the disk is connected with a path of anode reaction gas through an air inlet 6, an air-inlet duct 8 and an air-outlet duct 7 which are arranged in the disk rack and an air outlet 9. The proton exchange membrane flue cell of rotating disk type of the invention can evenly spread reaction gas on the surface of the cathode and anode in operation through self rotating of the rotating disk, actively and evenly discharge excess water, conveniently adjust humidity and temperature of the membrane and electrode and has comparatively high membrane utilization rate and low overall cost.

Description

Technical field: [0001] The invention relates to a fuel cell using a solid electrolyte, in particular to a proton exchange membrane fuel cell. Background technique: [0002] The known main structure of a single proton exchange membrane fuel cell includes an anode plate, an anode, a proton exchange membrane, a cathode, and a cathode plate stacked in sequence. The anode and the cathode are collectively referred to as electrodes, which are usually composed of conductive and good gas permeability carbon paper or carbon cloth, which are closely attached to the proton exchange membrane, and are evenly coated with carbon-supported platinum on the sides that are close to the proton exchange membrane. catalyst. During the operation of the proton exchange membrane fuel cell, it is necessary to supply the reaction gas to the electrodes. The anode reaction gas is generally hydrogen, the cathode reaction gas is generally oxygen, and the cathode is usually supplied with air in practical...

Problems solved by technology

Although the design of the tubular proton exchange membrane fuel cell achieves the purpose of separating the gas-conducting and conducting phases, it has disadvantages such as low power density per unit volume, difficulty in uniformly discharging heat generated during operation, and difficulty in achieving uniform humidity adjustment.
