September 07, 2000 by Jeff Shepard

Avista Corp. (Spokane, WA) technology subsidiary, Avista Labs, announced the issuance of US Patent 6,096,449 covering 73 claims for the electronic-control system that significantly enhances the performance of its modular, cartridge-based, proton-exchange membrane fuel cell. The new patent covers the control schemes that maximize the output of each modular cartridge and has been under review by the US Patent and Trademark Office for two years. Earlier this year, Avista Labs received a comprehensive patent for the modular design of its cartridge-based proton-exchange membrane fuel cell power system. "The bottom line is performance. The granting of this patent represents continued progress in our effort to deliver world-class fuel cells," said Avista Corp. Board Chairman, President and CEO T.M. Matthews. The cartridge-based fuel cell is designed to be reliable, simple and convenient, and the fuel cell cartridges can be easily removed and replaced while the power system continues to operate. "Today's patent grant reaffirms Avista Labs' position as a leader and innovator in proton-exchange membrane fuel cells," said Avista Labs President Kim Zentz. "Avista Labs continues to prove itself adept at developing innovative technology focused on the end-user."
