Abstract:
Hitachi Ltd. has demonstrated prototypes of a hyrocarbon thin-film battery cell and portable fuel cartridges that it hopes will help direct methanol fuel cells (DMFC) replace current batteries. Hitachi has been developing an electrolytic film made from hydrocarbon on which nanoscale metal catalyst is formed. The catalyst also functions as an electrode. Since catalyst particles combine, Hitachi developed a technology that maintains the metal catalyst in nanoscale particles, preventing cohesion that would otherwise decrease surface area and performance.
