Abstract

Nowadays, heavy environmental and economic pressure from energy consumption is increasingly evident, and the research and application of new batteries is an effective strategy to solve above problems. Fuel cell is a chemical device that produces electricity directly from chemical energy. It has attracted much attention due to its lightweight device, simple mechanism, and clean energy. In the operation of fuel cells, the efficiency and stability of cells are determined by the ability of catalyst in redox reactions. However, pure platinum or platinum-based catalysts commonly applicated in solid oxide fuel cells are normally expensive and not renewable. Therefore, it is particularly important to develop alternative Pt-based catalysts or non-Pt catalysts. In this paper, several alternative low-platinum or non-platinum catalysts are systematically investigated, and novel platinum-based and non-platinum multi-metal composite oxide catalysts are found to have higher catalytic activity and economic feasibility compared with pure platinum catalysts. The popularity of these new catalysts can effectively address the scarcity of resources and energy.
