Electrochemical energy conversion

Electrochemical energy conversion refers to the process of converting energy from one form to another using electrochemical reactions. This typically involves the conversion of chemical energy stored in fuels or batteries into electrical energy, or vice versa. The main systems involved in electrochemical energy conversion include: 1. **Fuel Cells**: These devices convert chemical energy directly into electrical energy through an electrochemical reaction, usually involving hydrogen and oxygen (or another oxidant).
