摘要：

The durability of the Phosphoric Acid Fuel Cell (PAFC) is greatly affected by the corrosion rate of carbon which is an essential material of PAFC. This study examines the influence of carbon material impurities on corrosion rates in hot phosphoric acid. Impurity doping was found to enhance oxidation of carbon materials in phosphoric acid. The influence of vanadium (V) and calcium (Ca), which were highly dispersed on the carbon surface, was significant. Impurity doping content was found to increase corrosion current.
