The H-20 is a newly designed upgraded fuel cell power system, that includes a 20W (rated) air-cooled, air-breathing and self-humidified PEM fuel cell stack with integrated fan in a mat black aluminium casing, a miniature pressure regulator and a 20L metal hydride storage system in a matching mat black canister. The H-20 is supplied with electronics to control the fuel cell system. The small fuel cell weighs only 230g and measures only 7.6 x 5.6 x 4.7 cm. At maximum power output, the H-20 system consumes 220 ml of H2 per minute, and has a peak power of 22W.
