CMR Fuel Cells Ltd. (Cambridge, MA) announced that it has developed a fuel cell battery that is one-tenth the size of other prototype units. CMR reports that the new design will run four times longer than conventional batteries in a laptop, or other devices like power tools. The design, which would run initially on methanol, was based on a new type of fuel stack, which is mixed air and fuel. Up to now, fuel stacks have relied on complete separation of the two.
The new fuel cell battery is also instantly rechargeable. The company came up with the design while working with consultancy Generics Group (Cambridge, MA). CMR is currently in talks about possible demonstrations for the US Defense Department.
