Fuel cells are non-polluting and efficient energy conversion devices that are expected to play a dominant role in energy solutions of the future. Main challenges for the commercialization of polymer electrolyte membrane fuel cells (PEMFCs) are the reduction of the high material cost and the improvement of the stability of fuel cells. In the current technology, a PEMFC typically utilizes a precious metal catalyst (such as Platinum or Platinum alloys) dispersed on a carbon black substrate and such a catalyst structure alone contributes as much as 50% to the total fuel cell cost. Another two problems to be solved are carbon monoxide poisoning of Pt-based catalysts and corrosion of carbon black.

燃料电池是无污染和高效的能量转换装置，预计将在未来的能源解决方案中发挥主导作用。聚合物电解质膜燃料电池（PEMFC）商业化的主要挑战是降低高材料成本和提高燃料电池的稳定性。在目前的技术中，PEMFC通常利用分散在炭黑基底上的贵金属催化剂（例如铂或铂合金），并且仅这种催化剂结构就占总燃料电池成本的50%。另外两个有待解决的问题是Pt基催化剂的一氧化碳中毒和炭黑的腐蚀。
