What are the applications of fuel power batteries?

Fuel power cell applications. Today, many types of fuel power cells have been developed according to different application requirements. According to the type of conductive ions, it can be divided into acid fuel power cells, alkaline fuel power cells, molten carbonate fuel power cells and solid oxide fuel power cells (SOFC). Acid fuel power cells can also be subdivided into PEMFC, direct alcohol fuel power cells and phosphoric acid fuel power cells. All kinds of fuel power batteries have their own working characteristics, the working temperature is as low as -40C and as high as 1000. The fuel power cell type can be selected according to different needs. Among them, PEMFC is the fuel power cell that has received the most attention in recent decades. PEMFC not only has the general characteristics of fuel power batteries, but also has outstanding advantages such as quick start and work at low temperatures, no electrolyte loss, long life, high specific power and high specific energy, and is considered to be the most ideal way to replace internal combustion engines as automotive power sources in the future. . Due to its modularity, wide power range, and diversified fuels, fuel power batteries can be used in a variety of applications: as small as power supplies for scooters, mobile charging devices, and as large as megawatt-level power stations. In fact, the commercialization of fuel power cells is proceeding like a fire. According to data, from 2008 to 2011, the worldwide market share of fuel power batteries as a backup power source for communication network equipment, logistics and airport ground handling increased by 214%. It is estimated that by 2020, the total market value of fuel power cells will reach 19.2 billion US dollars. The research progress of fuel power battery is summarized and the specific application is briefly analyzed as follows: (1) The year-on-year increase in the sales of the portable power supply The portable power supply market has attracted many power supply technologies, and its products include: notebook computers, mobile phones, radios and other mobile power sources In order to facilitate the personal carrying of equipment, the basic requirements of portable mobile power supplies usually require the power supply to have the characteristics of high specific energy, light weight and small size. The energy density of fuel-powered batteries is usually 5 to 10 times that of rechargeable batteries, making them more competitive. In addition, the feature that fuel-powered batteries do not require additional charging also makes them suitable for longer life in the wild. At present, direct methanol fuel power cells (DMFC) and PEMFC have been used as military individual power sources and mobile charging devices. Cost, stability and longevity will be the technical problems to be solved when the fuel power cell is applied to the portable power bank. (2) Fixed power supply Fixed power supply includes emergency backup power supply, uninterrupted power therapy, and independent power stations in remote areas. At present, fuel power batteries account for about 70% of the world’s megawatt-class fixed power supply market each year. Compared with traditional lead-acid batteries, fuel-power batteries have a longer running time (approximately 5 times that of lead-acid batteries). The specific energy density, smaller volume and better environmental adaptability. Regarding remote areas and emergency locations that are difficult to reach by smart grids, independent power stations are considered the most economical and reliable power supply method. In my country's many ground exhibition disasters, fuel power cells have been used as independent power stations, which have played an important role in disaster relief work. It should be noted that fixed power stations usually have a long life (more than 80,000 hours), which is the biggest technical challenge for the application of fuel power cell technology to fixed power stations. (3) Transportation power supply Transportation power supply has always been an important inducing factor for clean energy technology research and development, because 17% of the global greenhouse gas (CO2) is generated by fossil fuel-based transportation power, and other air pollution problems are also associated with it. , Such as smog and so on. PEMFC with H2 as fuel is considered to be the best alternative power for internal combustion engines. The important reasons are: (a) The exhaust gas is only water, without any pollutant emissions; (b) The working efficiency of fuel power cells is extremely high (53%-59%) , Almost twice that of traditional internal combustion engines; (c) Quick start at low temperature, low operating noise and stable operation. Many countries in the world are promoting fuel-powered cell transportation power methods, and Japan is one of the most radical countries. Japan plans to build more than 1,000 ammonia refueling stations and operate 2 million fuel-powered cell vehicles by 2025. In 2015, Toyota Motor Corporation of Japan began selling the Mirai, the world's first car with PEMFC as an important power source, marking a new era in the application of fuel cell technology to automotive power.
