Abstract: As a clean and effective new energy, fuel cell is regarded as one of the most important energy technologies. Proton conduction in solids has attracted much interest because of its potential application in fuel cells. Metal⁃oxalate compounds constructed by metal ions and oxalate are a sense of inorganic⁃organic hybrid compounds, which have emerged as a new class of proton conductors because of their controllable structures and high chemical variety. We summarized the proton conduction properties of main group⁃oxalate compounds, transition metal⁃oxalate compounds and lanthanide metal⁃oxalate compounds, and their future development was prospected.

Key words: Metal?oxalate compounds, Inorganic?organic hybrid compounds, Fuel cell, Proton conduction

摘要： 燃料电池作为一种清洁有效的新型能源被认为是最重要的能源技术之一。具有质子传导性质的晶态固体材料因其在燃料电池中的应用引起了人们广泛的关注。金属⁃草酸化合物是由金属离子和草酸构筑的一种无机⁃有机杂化材料，由于其可控的结构及多样的化学组成已经成为了一类重要的质子传导材料。从主族金属⁃草酸化合物、过渡金属⁃草酸化合物、镧系金属⁃草酸化合物3方面对其质子传导性能进行了总结，并对其未来的发展进行了展望。
