The technology of the future is here today—now available to non-engineers! Build Your Own Fuel Cell contains complete, easy-to-follow illustrated instructions for building multiple types of proton exchange membrane (PEM) fuel cells, as well as templates for 6 PEM fuel cell types, including convection fuel cells and oxygen-hydrogen fuel cells. Monolithic and stack configurations are included. Two different low-tech fuel cell construction methods are covered: one requiring a bandsaw and drill press, and the other requiring only basic hand tools. Anyone with minimal skills and tools can produce high-quality fuel cells from readily available materials. This electrochemical device produces no pollution and emits no hazardous substances. Designed with fine craftsmanship, compact size, portability, and ease of use in mind. Color: Photo Color. Material: Plastic. Package Contents: 1 x PEM Hydrogen Fuel Cell.
