Soluble and Highly Conductive Ionomer for High-Performance Hydroxide Exchange Membrane Fuel Cells

Soluble and Highly Conductive Ionomer for High-Performance Hydroxide Exchange Membrane Fuel Cells

Easy cell: The new polymeric ionomer TPQPOH with a tris(2,4,6‐trimethoxyphenyl)phosphonium unit has excellent solubility in some low‐boiling‐point water‐soluble solvents, high ionic conductivity, and outstanding alkaline stability. A hydroxide exchange membrane fuel cell containing this ionomer exhi...

Zusammenfassung:Easy cell: The new polymeric ionomer TPQPOH with a tris(2,4,6‐trimethoxyphenyl)phosphonium unit has excellent solubility in some low‐boiling‐point water‐soluble solvents, high ionic conductivity, and outstanding alkaline stability. A hydroxide exchange membrane fuel cell containing this ionomer exhibits increased peak power density and reduced internal resistance.
