近年来,直接乙醇燃料电池(DEFC)由于绿色环保、安全便携,燃料乙醇来源广泛、能量密度高等优势,逐渐引起人们的关注。而乙醇的电氧化过程复杂,中间产物多,C-C 键难以断裂,使得乙醇经过12 电子转移实现完全氧化生成二氧化碳的过程不易进行,造成能量损失。因此,制备一种新型高效的催化剂成为必然。
以直接涂布方式将催化剂加载于直子交换膜上而制作成三层式膜电极,其中直子交换膜采用厚度为20 微米、具有加强筋之全氟磺酸模材,而铂金催化剂加载量阴阳二极合计为0.6mg/cm2,气体扩散层采用SGL 24BC,气密垫圈厚度为各边160 微米.

催化剂的性能直接影响着燃料电池的性能与效率,碳材料广泛用于作为燃料电池催化剂载体,一旦碳载体发生腐蚀,碳表面将产生含氧官能团[1-3],削弱催化剂颗粒与碳载体的相互作用,使得催化剂颗粒团聚与迁移[1,4]。
直接甲酸燃料电池(DFAFC)作为高效、绿色可持续新动力能源被人们所亲睐。但甲酸电氧化过程较为复杂、产生的CO 易使催化剂中毒，因此制备高效、可行的催化剂对于DFAFC 的广泛应用至关重要。
