As we all know, solar energy is inexhaustible, and bioenergy is renewable. Both of these energy sources are clean and environmentally friendly. They are the two most important green energy sources in the world today. People have always been dedicated to the development and utilization of these two types of energy. Today, a new type of low-temperature fuel cell can combine them to produce electricity.
According to foreign media reports, scientists have developed a new type of low-temperature fuel cell, which is produced by grinding a biomass raw material and then mixing it with a polyoxometalate catalyst solution to generate a redox reaction under sunlight or heat radiation. Generate current. Biomass feedstock can be served by straw, sawdust, algae, organic fertilizers or water-soluble biomass and the like. Experiments have shown that the fuel cell catalyst can be reused without further treatment. Scientists believe that after optimizing the battery, the energy density will increase by 5 to 10 times. In the future, the performance of such a biomass fuel cell is even expected to be comparable to that of a methanol fuel cell, and its application prospects are very promising. (Wei Wei Li Zhongyue)
