Proton Exchange Membrane Fuel Cells (hereinafter referred to as fuel cell) is one kind without Carnot cycle, utilizes fuel (hydrogen
Gas) electrochemical reaction with oxidant (generally use air), chemical energy is converted into the power generator of electric energy.By proton
The fuel cell membrane electrode assembly (MEA) that exchange membrane is constituted with noble metal catalyst is the core component of fuel cell, in fuel
In the course of work of battery, MEA needs effectively to open fuel and oxidant barrier, prevents fuel from mixing direct hair with oxidant
Biochemical reaction rather than electrochemical reaction, possibly even set off an explosion under extreme case or fuel and oxidant it is mutual
Cell power generation efficiency caused by leakage declines and the decaying in service life.
In Proton Exchange Membrane Fuel Cells, anode and cathode Catalytic Layer be generally used carbon-supported nano Pt, Pd noble metal or its
Alloy is as catalyst.During electrochemistry occurs for fuel battery negative pole, the oxygen in air is through gas diffusion layers (GDL)
To proton exchange membrane diffusion, and the Hydrogen Proton that anode electrochemical reaction generates then penetrates proton exchange membrane and is transmitted toward cathode.Proton
With oxygen after noble metal catalyst Adsorption meets, the reduction reaction (ORR) that oxygen occurs generates water, two kinds of reactants
Matter is withered away.
Therefore, it in order to promote the specific power and energy conversion efficiency of fuel cell, how efficiently, consistently prepares in batches

Method be by catalyst pulp gas drainage by way of direct spraying in proton exchange membrane formed the straight film component of catalyst
(CCM).The method that another kind is more suitable for volume production is that catalyst pulp is directly coated on gas diffusion layers or transfer film, is led to
It crosses the method that hot pressing is transferred in proton exchange membrane and forms CCM.It has made CCM and has pasted carbon paper (GDL) and frame again later, and led to
The sizing of the moulding process such as punching, laser cutting, cross cutting is crossed, MEA products are ultimately formed.These techniques have generally lacked in CCM systems
Detection during work does not have if proton exchange membrane is leaky or has damaged proton exchange membrane during making CCM
There is timely detection, can all cause the waste of raw material, and in later stage MEA completes simultaneously detection process, then find not conforming to
Lattice product will substantially reduce production efficiency.And the CCD of CCM Catalytic Layers is detected, the consistency to producing membrane electrode performance has
It ensures, will greatly improve the generating efficiency of electrical materials and appliances battery.
The batch production and detection of membrane electrode are waited putting as described in patent CN201210438967.9 using constant-current supply
Electric MEA carries out constant current charge, current sensor measurement charging current, and data collector acquires the electric current letter of current sensor
Number and each batteries of fuel cell to be measured voltage signal, be converted into digital quantity signal and be transferred to data processing unit, data
Processing unit realizes that measurement data automatically processes by writing program, by each section fuel battery voltage data to acquisition into
Row differential and integral operation provide catalyst effective active area, electric double layer capacitance, the hydrogen infiltration of fuel cell membrane electrode to be measured
The parameters such as electric current and impedance, the method is more perfect in MEA context of detection, but there is no the detections for increasing making initial stage CCM
Link may cause the wastes of the materials such as MEA related components such as carbon paper, frame because CCM is unqualified, reduce production efficiency.
As described in patent CN200410093105.2, a kind of vacuum leak detector of fuel cell membrane electrode is provided, equipment is mainly wrapped
Including rack, mobile intermediate plate, cylinder, fixed test plate, activity detection plate, vacuum meter and stopcock.The method is less efficient, unfavorable
