The REXH2® is a marinized hydrogen power generator, built around a Toyota PEM fuel cell, which converts hydrogen into carbon-free electricity. This electricity can be used to power electric motors, on-board auxiliaries and to recharge batteries for all types of vessels, whether professional or pleasure. The REXH2® is an environmentally friendly product. It rejects only water and heat, which can be reused, and does not emit greenhouse gases or fine particles. It is also very quiet.
