本文回顾了过去几年在聚苯并咪唑和聚醚酮的功能化方面取得的进展，以期在不损害其热水解和化学稳定性的情况下提高其质子传导性能，从而使相应的膜可用于氢氧燃料电池或直接甲醇燃料电池。这些方法包括聚苯并咪唑与酸的络合、通过N-取代将含有磺酸部分的基团接枝到聚苯并咪唑上以及聚醚酮的直接磺化。另一种方法涉及在聚合物基质中掺入无机质子传导颗粒，这是针对混合磺化聚醚醚酮-金属（IV）磷酸盐膜的情况而详细开发的。 (C) 2001 Elsevier Science B.V. 保留所有权利。
This article reviews progress made over the past years in the functionalisation of polybenzimidazole and polyetherketones with a view to increasing their proton conduction properties without detriment to their thermohydrolytic and chemical stability such that corresponding membranes may be employed in hydrogen oxygen lair) or direct methanol fuel cells. The approaches include complexation of polybenzimidazole with acids, grafting of groups containing sulfonic acid moieties on to polybenzimidazole by N-substitution, and direct sulfonation of polyetherketones. A further approach concerns the incorporation of inorganic proton conducting particles in the polymer matrix, and this is developed in detail for the case of hybrid sulfonated polyetheretherketone-metal(IV) phosphate membranes.
