“…[ 1 , 2 , 3 , 4 , 5 ] Among diverse renewable energy devices, fuel cells, especially liquid alcohol fuel cells (AFCs), have received much attention due to their high energy density, minimal environmental hazards, compact design, quick start‐up time, low operating temperature, and ease of handling. [ 6 , 7 ] Significant research has been focused primarily on the commercialization of direct methanol (C1) fuel cells (DMFCs) due to their high energy density, rich supply, renewability, and easy affordability. In the same way, C2‐type ethylene glycol (EG) (C 2 H 6 O 2 ) [ 8 , 9 , 10 ] and C3‐type glycerol (C 3 H 8 O 3 ) [ 11 , 12 , 13 , 14 ] alcohols, which have high theoretical energy density and lower volatility, are also alternatives for the commercialization of multiple types of AFCs.…”
