SAIT Develops Fuel Cell for Cellular Phone
Samsung Advanced Institute of Technology (SAIT, Korea) has developed a fuel cell that can be built into a cellular phone, and which can be attached to the back of a cellular phone for use.
The size of a credit card, the direct methanol fuel cell features an output density of 32mW/cm2 (output is 2,000mW) and 50mW/cm2 at maximum (output is 2,600mA). The methanol crossover of the electrolytic membrane is reduced by 30 percent, resulting in an output-density increase to 180mW/cm2 at +80 degrees C, 100mW/cm2 at +30 degrees C, and 32mW/cm2 at +20 degrees C.
The new fuel cell is to be commercialized some time in 2004 to 2005.
