Power generation system coupling photocatalytic reduction of carbon dioxide and photocatalytic fuel cells

Abstract

The invention discloses a power generation system coupling photocatalytic reduction of carbon dioxide and photocatalytic fuel cells. A reaction block is internally provided with a vertically cut-through reaction chamber, and the left end and right end of the reaction block are respectively provided with a liquid inlet and a liquid outlet that are communicated with the reaction chamber. The upper end opening of the reaction chamber is sealed by upper conductive glass, the upper conductive glass surface facing the reaction chamber is coated with a photocatalyst. The lower end opening of the reaction chamber is sealed by a seal plate, which is formed by splicing of left lower conductive glass and a right carbon cloth, the carbon cloth surface facing the reaction chamber is coated with a platinum black catalyst, and the carbon paper is connected to the upper conductive glass through a lead. The system provided by the invention integrates photocatalytic reduction of carbon dioxide and power generation of photocatalytic fuel cells, couples the two reaction processes, reduces the raw material cost of fuel cells, and realizes zero discharge of carbon dioxide.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to an electricity generation system utilizing photocatalytic technology. Background technique [0002] In recent years, the use of solar photocatalysis technology to oxidize carbon dioxide and water into hydrocarbon fuels has attracted much attention. It can reduce atmospheric carbon dioxide and convert carbon dioxide into usable fuels, such as methanol, formic acid, methane, etc., which are expected to Solving the two major problems of the greenhouse effect and the energy crisis at the same time has great application potential. The reaction only needs to be carried out under normal temperature and pressure conditions. The photocatalytic conversion technology with solar energy as the direct driving force has therefore become an ideal way, and at the same time, it has attracted the research interest of many scientific researchers. [0003] On the other hand, solar photocatalytic fuel cell...
