The reversible PEM fuel cell combines the functions of an electrolyzer and a fuel cell into ONE device.

When applying an electrical current the device acts as an electrolyzer that produces hydrogen and oxygen from de-ionized water. When applying a load, the device behaves as a fuel cell and generates electricity from hydrogen.

Its electrolyzer function can use power from solar cells, miniature wind turbines, or batteries or mechanical hand cranks. Perfect for school science labs, classroom use or demonstration purposes.
