摘 要：The electrodes in Unitized Reversible Fuel Cell system with supported platinum carbon black are reported.However, the electrodes in the system is consist two internal modes; it is electrolyzer and fuel cell mode.A Unitized Reversible Fuel Cell has dual function electrodes are joined in the same cell to reduce the volume and improvement efficiency performance.The electrodes of Unitized Reversible Fuel Cells operating on hydrogen and oxygen which have as high as efficiency at most the applications.Therefore, This article is concentrated on the preparation of bifunctional electrodes as design and material with low platinum loading and supported by platinum carbon black and characterization by using scanning electron microscopy.As well as, survey the latest literature on bifunctional electrodes and electrocatalysts to identify the major problems occur in design of the URFC electrodes.
