Platinum group metal-free Fe-based (Fe N C) oxygen reduction electrocatalysts for direct alcohol fuel cells
نویسندگان
چکیده
In direct alcohol fuel cells (DAFCs), the oxidation of alcohols happens at expenses oxygen reduction reaction cathode. DAFCs' cathodes use a significant amount platinum that is an expensive critical raw material. Moreover, oxidizes alcohols, fact combined with crossover, decreases significantly performance cells. The Fe-based (FeNC) group metal–free (PGM-free) convenient strategy to overcome these limitations. This review analyzes application PGM-free DAFCs. discussion focuses on acidic systems and covers following subjects: (i) breakdown DAFC potential in its components, (ii) analysis advantages from cathode, (iii) durability closes view authors future perspective for research.
