Abstract
The fuel composition for a fuel cell for a polymer electrolyte membrane fuel cell includes a fuel, water, hydrogen peroxide (H2O2), and heteropoly acid. The fuel may be a hydrocarbon fuel. The hydrogen peroxide may be present in an amount of 10 wt % to 60 wt % based on the weight of the mixture of the fuel, water, and the hydrogen peroxide. The heteropoly acid may be present in an amount of 0.0001 parts to 5 parts by weight based on 100 parts by weight of a mixture of the fuel, water, and hydrogen peroxide. The fuel composition may reduce a reforming reaction temperature and also hydrogen generating efficiency and resultantly provides a high power cell.
