Abstract :
No matter how much wireless vendors improve their processors, memory systems, and networks, it does no good if a mobile device´s battery dies or has such a short life that users are virtually tethered to an electrical outlet. With this in mind, researchers are seeking to improve portable-power technology, and many are exploring a single alternative: fuel cells.
