Development of high-durability single-atomic catalyst using industrial humidifier

Fuel cell electric vehicles (FCEVs) are an eco-friendly means of transportation that will replace internal combustion locomotives. FCEVs offer several advantages such as short charging time and long mileage. However, the excessive cost of platinum used as a fuel cell catalyst leads to limited supply of FCEVs. There has been extensive research on non-precious metal catalysts such as iron and cobalt to replace platinum; however, it is still challenging to find substitutes for platinum due to low performance and low stability of non-precious metal catalysts.
