The demand for ever more functions and higher processing speed in mobile devices has raised the energy consumption of such devices beyond the capability of low-energy-density and long-charging-hour lithium batteries. As an energy source, fuel cells are much better than lithium batteries due to their higher energy density and faster charging speed. Of the many types of fuel cell, the DBFC appears to be the best alternative for mobile devices because of its higher energy density, better performance at low temperature and more compact structure. This research will study such DBFC parameters as the proportions of membranes, catalyst, fuel and temperature in order to achieve the best result for supplying power to mobile devices, and compare these characteristics with the popular DMFC to further develop the most suitable fuel cell for portable electronic products. |
