The main challenges for commercialization of fuel cells are cost and durability. Using off-the-shelf materials for system components in Proton Exchange Membrane Fuel Cells (PEMFCs) may lower the cost provided they do not compromise function, fuel cel

Cationic headgroups such as tetramethylammonium (TMA) undergo degradation in alkaline conditions through two different mechanisms. In the first mechanism, a hydroxide ion performs an SN2 attack on the methyl groups and directly forms methanol. In the
