A local high-tech company recently realized the first commercial use of hydrogen fuel cells in China. Eight of its independently developed batteries have been used at a China Unicom base station in Jiangsu province for stand-by power. According to the developer, the hydrogen fuel cell has a lifespan that is two to three times longer than the traditional lead-acid battery that the base station used before. It also cuts operational costs in half. In addition to the communications industry, this clean energy technology can also be used for elevator lighting and to provide power backup systems for financial data centers.
