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.
