Hydrogen energy is an important trend of energy transition in the future. Compared with solar energy, wind and water energy and other energy sources that are limited by geography and seasons, hydrogen energy has the advantages of being green, clean and non-polluting, producing no carbon dioxide when consumed, and being stored in various forms for a long period of time, which makes it a key direction for the development of emerging industries and future industries. Hydrogen and fuel cell testing solutions meet the requirements of fuel cell engine testing, fuel cell stack, fuel cell DCDC testing, charging pile aging testing, hydrogen production from alkaline water electrolysis, hydrogen production from PEM electrolyzer water, and so on.
