Proton Conducting Mechanism during Fuel Cell Operation I 415... 

During fuel cell operation, ions would conduct through PEMs, which leads to current flow in the cell system. Thus, the conductivity of PEMs plays an important role in fuel cell performances, and membrane conduction mechanism has drawn much attention in fuel cell researches. There are mainly two kinds of conduction mediums in PEMs according to the fuel cell type proton (H+) and hydroxyl (OH ). As aliphatic membranes were usually used for anion-conduction membrane and proton-conduction mechanism has been discussed already in the preceding chapters, we will focus our attention mainly to hydroxyl conduction mechanism in this chapter, although they have a lot in common.
