Fuel Cell Assembly Patent For Sale    

An innovative technology used to prevent power loss in fuel cell assembly.


Offered IP describes the Proton Exchange Membrane (PEM) Fuel Cell component constructed in a novel way and with use of the most technologically advanced materials. The invention is targeting improvements in fuel cells electrical current density, mechanical integrity, operational life time and reduction of the internal electrical losses as well as efficiency of the fuel consumption and effectiveness of reaction product (water) removal. Additional benefit of this invention is its applicability in the Fuel Cell Stack powering portable and highly miniaturized special medical instrumentation and personal/consumer multimedia devices with possibility for a long operational time and rapid refueling.

The seller would like to be granted a license back.
