Ionomer membranes general discussion

Comprehensive reviews and discussions of ionomers can be found in a number of monographs and review articles (55-64). Four general topics are discussed here (1) new materials, (2) structure, (3) solutions, and (4) membranes. 

The general behavior of the membrane with cation contamination, with and without the water effects, is presented and discussed based on predictions from the model. The model is extended to include the potential from the metal on each side into and through the ionomer in the electrodes. Because the work is focused on the membrane, this aspect is restricted to only include a hydrogen pump cell with hydrogen electrodes on both the anode and cathode sides.
