using a fuel cell to separate water into hydrogen and oxygen is chemical separation.
- fuel cell uses concept of called reversible electrolysis for seperation.
- The process of separating water into hydrogen and oxygen is known as electrolysis.
- An electrolyte separates the anode from the cathode in a fuel cell. Different types of electrolyte and the ionic species they conduct play a major role in how different fuel cells operate.
- At the anode, water reacts to produce positively charged hydrogen ions and oxygen (protons).
- The hydrogen ions move arbitrarily across the to the cathode as the electrons go through an external circuit.
- Hydrogen gas is created at the cathode when hydrogen ions and electrons from the external circuit combine.
- In order to reach the Hydrogen Energy Earthshot objective of lowering the price of clean hydrogen by 80% to $1 per kilogramme in ten years, electrolysis is a primary method of hydrogen production.
