South Korean media reported that researchers said on the 28th that some Korean scientists have developed a proton ceramic fuel power cell with greatly improved performance and scalability, which will help promote the commercialization of the next-generation ecological power generation system. Proton ceramic fuel power cells can be used to power off-grid huts in remote areas and to power backup generators in the event of natural disasters. Researchers at the Colorado School of Mines have stated that this relatively new type of fuel power cell has long-term durability and fuel flexibility, making it a viable commercial alternative to other existing fuel power cell technologies. According to Yonhap News Agency’s report on August 28, the joint team headed by Lee Jong-ho of Korea Institute of Science and Technology and Shin Dong-wook of Hanyang University said that they meet the high performance and cost-efficiency of next-generation fuel power cells. Requirements. According to reports, in recent decades, proton ceramic fuel power cells have been hailed as the next generation technology. However, due to the fire resistance and low chemical stability of proton-conducting ceramic electrolytes, proton-ceramic fuel power cells have to break through performance limitations. The researchers said that by performing anode-assisted thickening of a proton-conducting electrolyte on an anode support with uniform structure and composition, they have produced the best known performance of a proton ceramic fuel power cell. According to the report, the research results were published on the website of the British 'Nature·Energy' magazine. In total, the researchers detected 11 different fuels-hydrogen, methane, domestic natural gas (with and without hydrogen sulfide), propane, n-butane, isobutane, isooctane, methanol, ethanol and ammonia- During thousands of hours of operation, the researchers continued to change fuel for detection. Proton Ceramic Fuel Power Cells (PCFC) are very flexible and can use a variety of different actual fuels and produce electricity. This is completely different from other fuel power cells that only use hydrogen. Some high-temperature solid oxide fuel power cells (SOFCs) can also use other fuels, but they are still picky. Using other fuels, they are susceptible to pollution and degradation, and Its performance declines rapidly over time. The performance probes conducted by the researchers at the Colorado School of Mines lasted 10 times longer than any previous probes. Regarding these detections, Duan designed and built a fuel-powered battery detection system that can simultaneously detect seven batteries using different fuels for thousands of hours. The longest detection is 8,000 hours, which is almost a year. The degradation rate of most fuel power cells is less than 3% per 1,000 hours, which meets the requirements of commercial products. Mining researchers are currently working with FuelCellEnergy, a fuel cell company located in Connecticut, to expand laboratory-scale technology and develop pre-commercial prototypes that can supply the electricity needed to power RVs or remote cabins. From the Advanced Research Projects Agency of the United States Department of Energy Granted by the Energy Agency (ARPA-E) through its Reliable Electricity Based on Electrochemical System (REbELS) program.
