QuantumSphere Inc. says it has perfected the manufacture of highly reactive catalytic nanoparticle coatings that could up the efficiency of electrolysis, the technique that generates hydrogen from water. Moreover, the coatings could also eliminate the need for expensive metals like platinum in hydrogen fuel cells.
The coatings can be used to retrofit existing electrolysers to increase their efficiency to 85 percent–exceeding the Department of Energy’s goal for 2010 by 10 percent.
“Instead of switching 170,000 gas stations over to hydrogen, using our electrodes could enable consumers to make their own hydrogen, either in the garage or right on the vehicle,” said Kevin Maloney, president, chief executive officer and co-founder of QuantumSphere. “Our nanoparticle-coated electrodes make electrolysers efficient enough to provide hydrogen on demand from a tank of distilled water in your car.”
The first commercial product inspired by QuantumSphere’s technology will debut later this year: a battery using a cathode coated with the startup’s nanoparticles, thereby increasing its energy density 5x over alkaline cells and boosting power by 320 percent. The first commercial nonrechargeable batteries with this increased capacity will be announced by an as-yet-unnamed major U.S. battery maker in the second half of 2008.
