Hydrogen tungsten bronze (HxWO3, 0≤x≤1) may be used as a co-catalyst in combination with platinum, thereby reducing the usage amount of platinum (The cost of platinum is high) and increasing the catalytic activity of platinum. Hydrogen tungsten bronze combines with the adsorbed hydrogen which has not been completely dissociated on platinum surface, thus increasing the rate of hydrogen oxidation reaction. At the same time, HxWO3 has the ability to provide protons after accepting a large number of protons. These protons…
