A highly durable pore‐filling‐type electrolyte membrane for direct methanol fuel cells has been developed from a porous polyimide substrate and a wholly aromatic hydrocarbon (see figure). The membrane succeeds in reducing the methanol crossover to several hundred times lower than that of a commercial Nafion membrane.
