Review of the Electrodes Layer for Unitized Regenerative Proton Exchange Membrane Fuel Cells

摘要

Regenerative Fuel Cell can be used to store energy from renewable resources as solar and wind energy. Such systems consist of electrolyzer and fuel cell. In Unitized Regenerative of Proton Exchange Membrane Fuel Cells both functions are combined at same stack to allowing a cost and volume reduction and enhancement performance. Unitized Regenerative PEM Fuel Cells operating on hydrogen and oxygen are being considered as high efficiency and power generators for stationary and transportation applications. However to penetrate these markets the cost of the fuel cells must be decresed. In this paper review the recent details made on the progress of reduction in the stack cost by lower platinum loadings in the latest URFC stack design. Although such advances are still a need for further reductions in the stack cost through development in the design and performance of the electrodes assembly of URFC. Therefore, the paper is focused on review the preparation of electrodes as design and material with low platinum loading and characterization by using scanning electron microscopy. Also survey the latest literature of electrodes and electrocatalysts to identify major components and materials of URFC stack.
