Embodiment
[0036] A proton exchange membrane fuel cell is an electrochemical device that uses the reverse reaction of electrolyzing water to generate electricity.
[0037] The electrochemical reaction equation of the two electrodes is as follows:
[0038] Anode: H 2 →2H + +2e -
[0039] cathode:
[0040] Total battery response:
[0041] The reaction products are DC electric energy, liquid water and heat of reaction.
[0042] The application object model of this example adopts the cell voltage V-I model proposed by J.C.Amphlett, and the basic expression of the output voltage of the cell is:
[0043] V cell =E Nernst -V act -V ohmic -V con (1)
[0044] where V cell is the road terminal voltage of the battery (V), E nernst ,V act ,V ohmic and V con They are battery thermodynamic voltage, activation polarization electromotive force, ohmic voltage drop and concentration overvoltage (V).
