Combustion of Hydrogen Gas
2H2 + O2 → 2H2O
概要
Hydrogen gas burns in oxygen to produce water with no carbon-containing products. This makes hydrogen the ultimate clean fuel. The reaction produces a very hot, nearly invisible flame. Hydrogen-oxygen mixtures are explosive within a wide flammability range (4-75% H2 in air).

日常の例
Hydrogen fuel cell vehicles like the Toyota Mirai emit only water vapor from the tailpipe, as the hydrogen effectively combusts electrochemically.
産業上の重要性
