Understanding how the presence of cations causes polymer electrolyte membranes to degrade is important to advancing PEM research. Fraunhofer ISE has been focused on analyzing various types of cations for their impact on perfluorosulfonic acid (PFSA) membranes. This analysis is significant in understanding the catalytic effect individual cations have on forming radicals that attack PFSA polymers. How chemical stable these polymers are was investigated using Fenton’s reaction.
Are batteries or fuel cells the more environmentally friendly, technically superior and economically prudent solution for electric transportation? Short answer: It depends.
