Neah Power’s direct-methanol fuel cells are lighter than batteries and less expensive than other fuel cells. Its novel silicon-based electrode has 40 times as much surface area as most fuel cells, producing more charge while using less platinum catalyst.
This fall, Neah introduced Infinity eL, its demo product line. The company usually tailors its tech to specific applications—for example, a 45-watt cell that can double a three-foot-wide unmanned aerial vehicle’s flying time, without adding weight. Neah cells could soon replace other portable products, including electric-car and laptop batteries.
