Research on Application of H2 Fuel Cell Backup Power System at Transformer Stations for Electric Power System

This article is aiming to illustrate the replacement of traditional lead-acid battery stacks with Hydrogen fuel cell products as backup power products to provide electricity for substation DC system.The article researches how to use H2 fuel cell power system as a integrated backup energy for DC system,as a removable DC power supply for emergency use,and tests the feasibility of using H2 fuel cell as backup power system during DC technological transformation.The author also proposes new backup power supply design and new solutions for the whole power system.According to such research and analysis,using H2 fuel cell to replace lead acid batteries as backup power system during blackout period can largely reduce CO2 pollution to the environment.
