Portable communication devices are extremely popular but mobile technology has its limits as batteries are quickly exhausted. Scientists have spent years trying to develop alternatives to lithium ion batteries with much hope being placed on fuel cells. After many setbacks in development, a small firm from Silicon Valley is showing that fuel cells may indeed be the way forward. In contrast to conventional lithium ion batteries, fuel cells cannot store a charge, but they do offer many other advantages. Fuel cells are easier and cheaper to make and you don’t need a wall outlet to fill them up. Fuel cells use gases such as methanol or hydrogen to source their power and they are also a lot more environment-friendly than normal mobile batteries. Fuel cells generate electricity in a chemical reaction where hydrogen or methanol are combined with oxygen. Electrical energy is released during the process which can be used to power a device. Along with electronics companies such as...
