What are the important types of fuel-powered batteries?

The main types of fuel power batteries are as follows: 1. Phosphate fuel power batteries Phosphate fuel power batteries are the earliest type of fuel power batteries. The process is basically mature. The United States and Japan have built 4500 kilowatts and 11,000 kilowatts respectively. Commercial power station. The operating temperature of this fuel-powered battery is 200°C, the maximum current density can reach 150 mA/cm2, and the power generation efficiency is about 45%. The fuel is preferably hydrogen, methanol, etc., and the oxidant is air, but the catalyst is a platinum series. The cost of power generation is still high, about 40-50 cents per kilowatt hour. 2. Melt carbonate fuel power battery Melt carbonate fuel power battery is generally called the second-generation fuel power battery. Its operating temperature is about 650℃, and its power generation efficiency is about 55%. Mitsubishi Corporation of Japan has built 10 kilowatts. Grade power generation device. The electrolyte of this fuel-powered battery is liquid. Due to the high working temperature, it can withstand the presence of carbon monoxide. The fuel can be hydrogen, carbon monoxide, natural gas, etc. Air is used as the oxidizer. The cost of power generation can be less than 40 cents per kilowatt hour. 3. Solid oxide fuel power battery The solid oxide fuel power battery is considered to be the third generation of fuel power battery. Its operating temperature is about 1000℃, and its power generation efficiency can exceed 60%. It is currently being studied in many countries. The construction of large-scale power stations is currently under development by Westinghouse. In addition, there are several types of fuel-powered batteries, such as alkaline fuel-powered batteries. The operating temperature is about 200°C, and the power generation efficiency can be as high as 60%, and no precious metals are used as catalysts. Sweden has developed a 200-kilowatt device for submarines. . The first small fuel-powered battery used in the Apollo spacecraft in the United States is called the American type. It is actually an ion-exchange membrane fuel-powered battery. Its power generation efficiency is as high as 75%. Later, the United States developed a fuel-powered battery for hydrogen-powered vehicles. It can be charged with hydrogen for 300 kilometers at a speed of 100 kilometers per hour. This is a reversible proton exchange membrane fuel-powered battery with a power generation efficiency of up to 80%.
