Canon said it has developed tiny fuel cells that it hopes will start replacing conventional batteries to power some of its digital cameras and printers in three years. Canon will join a small army of companies, including Toshiba, NEC, and Hitachi, that are working on the development and commercialization of fuel-cell batteries for the next-generation of consumer electronics. Fuel-cell technology mixes hydrogen and oxygen to generate electricity and is considered a promising replacement for today’s lithium-ion batteries, which are widely used to power a range of mobile products from notebook PCs to mobile phones.
