The principle of liquefied ammonia electrolysis

involves the electrochemical decomposition of ammonia (NH₃) using an electrolyte and electrodes to produce hydrogen (H₂) and nitrogen (N₂). This process is a highly efficient and eco-friendly method for hydrogen production, making it an attractive technology for clean energy solutions.

liquefied ammonia is introduced into an electrolytic cell along with an electrolyte. When an electric current is applied, the following reactions occur:

Chemical Structure of Ammonia
  • Ammonia is composed of nitrogen (N) and hydrogen (H), making it an ideal source for hydrogen extraction.
  • It can be decomposed with relatively low energy input, enabling efficient electrochemical reactions.
