阴离子膜燃料电池阴极非贵金属催化剂研究进展

Development of non-noble metal catalysts for oxygen reduction in alkaline exchange membrane fuel cells

与质子交换膜燃料电池相比,阴离子交换膜燃料电池不仅能显著提高阴极氧还原反应(ORR)动力学,而且可采用非贵金属催化剂大幅降低成本和减少极板腐蚀,成为新能源领域中的研究热点。对阴离子膜燃料电池中阴极非贵金属氧还原催化剂的研究进展进行了详细评述,在此基础上提出杂原子掺杂的多孔纳米碳材料和以其为载体担载合金化的非贵金属是阴离子交换膜燃料电池阴极催化剂今后的发展方向。

Compared with the proton exchange membrane fuel cell(PEMFC),the anion exchange membrane fuel cell(APEMFC)using non-noble metal as their catalyst not only improve the cathodic oxygen reduction reaction(ORR)dynamics,but also reduce costs and the plate corrosion.APEMFC has become a hot research topic in the new energy field.In this paper,the developments of non-noble metal catalysts for oxygen reduction in APEMFCs were reviewed.On the basis of this,the porous nano carbon materials doped with hetero atoms and the non-noble metals supported on the carrier were proposed,which could be the future development direction of APEMFC cathode catalyst.
