What is a Fuel Cell？ If you want to know the technical information about it, a fuel cell is an electrochemical energy conversion device. A fuel cell converts the chemicals hydrogen and oxygen into water, and during the process it produces electricity, so it is suitable for every kind of small mobile power device.
The object of this thesis is to fabricate and compare the perform of proton exchange membrane fuel cell. The flow field used reformation flow field type where the active area of the membrane is 14cm×14cm single cell. The effects of different operating parameters on the performance of proton exchange membrane fuel cell have been studied experimentally using pure hydrogen on the anode side and pure oxygen or air on the cathode side. Experiments with different cathode and anode humidification temperatures, different oxidant of these parameters have been carried out.
Above all, the experiment and analysis of a serial of parameter through, the result shall be the key factor which be carried and affect the characteristics of PEM fuel cell.In the single cell with 14cm x 14cm active area, to improve fuel gas of humidification temperature can promote obviously performance of the fuel cell. From the experiment results, the performance of oxygen type module is better than that of air type, because the oxygen content is less in the air type. The experimental results are presented in the form of polarization curves, which show the effects of the various operating parameters on the performance of the PEM fuel cell.
