With the rapid development of the industry worldwide, the mainly used fossil fuels currently can no longer meet the increasing energy demand. In addition, the energy transformation efficiency of fossil fuels is low and their reserves are limited. The emitted gases contain pollutants such as CO, NO, and sulfides, which seriously pollute the environment. Therefore, a new round of energy technology changes is booming, and the development and utilization of efficient and clean new energy sources has become a major concern worldwide.
