The technology of the future is here todaynow available to everyone! Build Your Own Fuel Cell provides complete, easy-to-follow illustrated instructions for building multiple types of proton exchange membrane (PEM) fuel cells. Includes templates for six PEM fuel cell types, such as convection fuel cells and oxygen-hydrogen fuel cells, in both monolithic and stack configurations. Covers two low-tech construction methods: one using a bandsaw and drill press, and another using basic hand tools. Anyone with minimal skills and common tools can create high-quality fuel cells from readily available materials. This electrochemical device produces no pollution and has zero hazardous emissions. Features precise workmanship, a compact design, and portability for easy use. Color: Photo Color. Material: Plastic. Package Contents: 1x PEM Hydrogen Fuel Cell. Note: Other items shown are not included. Lighting and display differences may cause slight color variations between the image and the actual product. Measurement tolerance: +/- 1-3 cm.
