Fuel Cell Research Based on Electrochemical Analysis

Abstract

With the development of social economy and the improvement of people's living level, the global energy demand is rising rapidly. The reserves of traditional fossil energy such as coal, oil and natural gas are limited, and its depletion is inevitable. And the massive use of fossil energy will also bring a series of environmental problems such as greenhouse effect. Therefore, it is urgent to find a clean and renewable energy. Fuel cell (FC) is a new energy technology that has attracted much attention. It is a power generation system that converts the chemical energy of fossil fuel (coal, oil, natural gas, etc.), biomass fuel or other hydrocarbon fuel (ethanol, propane, butane, etc.) into electrical energy directly without combustion through electrochemical reaction. In the process of fuel cell operation, fuel and air react in different chambers respectively, breaking away from the restriction of Carnot cycle. In this way, the utilization rate of fuel has been greatly improved. Moreover, the fuel cell will only produce H2O, CO2 and other products in the working process, and will not produce dust or other harmful gases. Therefore, the research and development of efficient and clean new energy technology is of great significance to promote the rational use of coal resources and biomass fuel and coordinate the harmonious development of environment and economy.
