Electrolyzer and Fuel Cell Membranes: Alkaline, PEM and AEM Compared

Why watch it?

In this Hyfindr Tech Talk, Tim Wu of Hyproof explains what membranes do in electrolyzers and fuel cells. According to the description, alkaline systems are older and cheaper but their wide pores raise safety concerns, PEM is efficient but needs costly catalysts such as platinum, and AEM aims to combine both without expensive catalysts. Membranes versus diaphragms, lifetime and manufacturing get separate segments. Wu works for a membrane company, so the case for AEM may reflect that view.
