Ionic current between the anode and the cathode is transported through an ionic conductor. In low-temperature fuel cells, internal charge carriers are protons and the proton conductor is a solid polymer electroljde membrane (typically Nafion ). It took more than 10 years to clarify the mechanism of proton transport in this membrane. However, the membrane structure and its dependence on water content are still unclear.

This chapter has been divided into seven sections that are devoted to different media, in which proton transport occurs. We will start in Section 2 with a discussion of transport in liquids including the well-studied case of water, continuing with transport in biomolecules in Section 3. Sections 4 and 5 are dealing with transport in solid-state materials and the liquid-solid interface. For Section 6 we have chosen proton-transport in materials that are used or proposed as fuel-cell membranes as a final topic. In Section 7 we conclude. 

We have in the present version of the treatment of electrochemical transport omitted many cases. These include a more full coverage of proton transport in oxides and transport by other hydrogen species and other foreign species. Moreover, we have left out the case of solid-solid reactions. Also, creep and sintering were given more phenomenological than defect-chemical treatments.
