A convenient and realistic ex-situ method for determining the degradation rate of hydroxide-exchange-membranes for fuel cell applications
The application of anion exchange membranes (AEM) in their hydroxide (OH–) form (sometimes denoted by HEM) as separators in low temperature fuel cells is a matter of ongoing research. OH– conductivity close to the proton conductivity of PEMs (such as the well-established Nafion®) are quite common [i] for high levels of hydration, and the reactivity of OH– with CO2 in air (used as oxidant in fuel c
