How does fuel cell operate

Explanation

**Step-by-Step Solution: How a Fuel Cell Operates**

1. **Introduction to Fuel Cells**: A fuel cell is an electrochemical device that converts the chemical energy of a fuel (commonly hydrogen) and an oxidant (commonly oxygen) into electricity through an electrochemical reaction.

2. **Components of a Fuel Cell**: A typical fuel cell consists of two electrodes: an anode and a cathode, separated by an electrolyte. The anode is where oxidation occurs, and the cathode is where reduction takes place.

3. **Oxidation at the Anode**: In a hydrogen-oxygen fuel cell, hydrogen gas (H₂) is supplied to the anode. At the anode, hydrogen molecules undergo oxidation:
