(Phys.org)—As scientists look for alternative energy sources,fuel cells that operate in a basic environment believe garnered much attention. Typically fuel cells require an expensive catalyst, such as platinum. Hydroxide exchange fuel cells involve the movement of hydroxide ions (OH-) across a polymer membrane. The alkaline environment is conducive to the oxidation and reduction reactions without the need for expensive metals. However, or these reactions are quite late requiring a better catalyst.
