Electrochemical clean energy devices

Supercapacitors

Supercapacitors, or electric double-layer capacitors (EDLCs), store energy by adsorbing and desorbing electrolyte ions on the electrode surface without redox reactions. This enables fast charge/discharge rates and long-lasting performance.

Fuel cells

A proton exchange membrane fuel cell (PEMFC) converts chemical energy from the reaction between hydrogen and oxygen into electrical energy. Hydrogen is supplied to the anode, where it is catalytically separated into protons and electrons. The protons pass through the polymer electrolyte membrane to the cathode, while the electrons travel through an external circuit, generating electricity. At the cathode, oxygen combines with the protons and electrons, forming water as the only byproduct.

Batteries

A battery is an electrochemical device that stores chemical energy and converts it into electrical energy through oxidation at the anode and reduction at the cathode, supplying power to electrical circuits and devices.
