Angstrom Power’s micro hydrogen fuel cells can be sized to fit in existing cell phone battery spaces and can be recharged in just 10 minutes.ÃÂ It’s no wonder that Motorola was keen toÃÂ replace lithium ion batteries withÃÂ Angstrom’s fuel cells.ÃÂ As Green Tech Gazette reported, Motorola has put the micro hydrogenÃÂ fuel cells in its MOTOSVR L7 cell phone, which wasÃÂ on displayÃÂ at the Consumer Electronics Show in January.ÃÂ
Angstrom has a number of patents covering its fuel cell technology.àU.S. Patent Nos. 6,864,010 and 6,969,563 are directed to high power density fuel cells using the company’sàspecial micro-structured architecture.àUnlike conventional fuel cell designs, whichàinclude discrete gas diffusion layers, catalyst layers and electrolyte layers, Angstrom’s fuel cells integrate the functions ofàall three layers into a single porous substrate.àTheàthree “layers”àcan beàfolded together to form various shapes.àIn addition, Angstrom’s porous micro-structure increases the electrochemically active surface area of the fuel cell. àThe resulting high energy density fuel cells are well-suited for small portable consumer electronics.
