This German/Korean joint proposal (DFG / NRF) represents a fundamental study of a membrane electrode assembly (MEA) for a high-temperature polymer electrolyte fuel cell (HT-PEMFC) system working at temperatures well above 100°C without the need of humidifying the feed gas. The membrane will be a composite consisting of an appropriate carrier polymer and an appropriate proton conducting ionic liquid (PIL), i.e. will be an alternative to HT-PEMFCs based on polybenzimidazole doped with phosphoric acid, the present state-of-the-art. The Korean partner is a specialist for polymer electrolyte membranes and will prepare those in such a way that appropriate ionic liquids can be adsorbed at inner interfaces or even chemisorbed (covalently bonded?). The German partner has a long-lasting experience with ionic liquids; he will identify and synthesize these appropriate ionic liquids. Both partners will test the proton conductivity of these polymer/ionic liquid composites and will try to elucidate the proton conductivity mechanism in polymer/ionic liquid composites. The German partner is also a specialist for electro-catalysis; he will identify and prepare appropriate electro-catalysts and try to elucidate the mechanism of the oxygen reduction reaction, which in PEMFCs is always rate-determining. Fuel cells running at temperatures well above 100 °C allow the use of their waste heat for heating purposes (combined heat and power). Fuel cell tests with the innovative MEAs developed in this project will be conducted at both research locations.

该德国/韩国联合提案（DFG / NRF）代表了用于高温聚合物电解质燃料电池（HT-PEMFC）系统的膜电极组件（MEA）的基础研究，该系统在远高于100°C的温度下工作，而无需对进料气体进行脱硫。该膜将是由适当的载体聚合物和适当的质子传导离子液体（PIL）组成的复合材料，即将是基于掺杂有磷酸的聚苯并咪唑的HT-PEMFC的替代物，目前的状况韩国合作伙伴是聚合物电解质膜的专家，并将以适当的离子液体可以吸附在内部界面甚至化学吸附（共价键合？）。德国合作伙伴在离子液体方面拥有长期的经验;他将识别和合成这些合适的离子液体。双方将测试这些聚合物/离子液体复合材料的质子传导性，并试图阐明聚合物/离子液体复合材料中的质子传导机制。德国合作伙伴也是电催化方面的专家;他将识别和制备适当的电催化剂，并试图阐明氧还原反应的机理，这在PEMFC中总是决定速率。在远高于100 °C的温度下运行的燃料电池允许将其废热用于加热目的（热电联产）。燃料电池测试与创新的多边环境协定在这个项目中开发的将在两个研究地点进行。
