FT. LAUDERDALE, Fla., Sept. 15 /PRNewswire-FirstCall/ -- EnerFuel, Inc., the fuel cell subsidiary of alternative energy technology company Ener1, Inc. (OTC Bulletin Board: ENEI), today announced it has received a Notice of Allowance from the United States Patent & Trademark Office for a new patent for an integrated feedback control system that is designed to improve the safety, reliability and lifetime of Proton Exchange Membrane (PEM) fuel cells. The integrated feedback control system is designed to allow PEM fuel cells to operate more efficiently under variable loads, such as those encountered during the braking and accelerating of a fuel cell vehicle. The system is also designed to prevent the drying out of the fuel cell membrane, which can cause the fuel cell to quickly deteriorate and may lead to safety hazards, including fire. Both of these design features address critical factors for the commercialization of hydrogen technologies in transportation applications. "EnerFuel has made great strides in developing its unique technologies and know-how as demonstrated by this most recent patent allowance," said Kevin Fitzgerald, Chairman and Chief Executive Officer of Ener1. "The company is focused on delivering fuel cell manufacturers and the industry at large innovations that will advance the safety and performance of their fuel cells, and thus help make hydrogen energy a commercial reality sooner." EnerFuel's control system design incorporates a novel self-regulating feedback mechanism that supplies hydrogen and air to the anode and cathode of the fuel cell stack by using a system of pressure regulators and pumps. The feedback system controls the flow of fuel and oxidant gases required to maintain and maximize the electrochemical reaction of the fuel cell stack under varying current loads. Other features of the fuel cell control system include the ability to regulate the water concentration, which is critical to the long-term operation of the fuel cell system. Without proper water regulation (a by-product of the electrochemical reaction of a fuel cell), over drying of the fuel cell can occur. When fuel cell membranes become dehydrated, holes or voids in the fuel cell membrane can occur, resulting in the risk of fire or explosion from the direct mixing of hydrogen and oxygen. The EnerFuel control system is designed to essentially eliminate this potential safety hazard.
