alkaline fuel cells

Alkaline fuel cells (AFCs) are energy devices that convert chemical energy from hydrogen and oxygen into electricity, using an alkaline electrolyte (like potassium hydroxide). When hydrogen gas enters the cell, it splits into protons and electrons. The electrons create electricity as they flow through an external circuit, while the protons move through the electrolyte to meet oxygen, forming water as a byproduct. AFCs are efficient and can operate at lower temperatures compared to other fuel cells. They have been used in space missions and are being explored for clean energy applications on Earth.
