Latest Breakthrough from PolyFuel, Inc. Enables Portable Fuel Cell to Pass 5,000-Hour Lifetime Mark

PolyFuel, Inc., announced that its hydrocarbon DMFC (direct methanol fuel cell) membrane has passed the 5,000-hour mark in durability testing. Jim Balcom, CEO of PolyFuel, tells NWN, “[Our company’s] hydrocarbon DMFC membrane has many advantages, including the ability to make portable fuel cell systems smaller, lighter and longer running when compared with conventional fluorocarbon membranes.”

This is an important milestone in the development of fuel cells for portable electronics, including cell phones, laptop computers, and PDAs. The runtime of the typical 4-hour laptop battery drops to about 2.5 hours after 3,000 hours of use. A fuel cell using PolyFuel’s membrane continues to deliver original levels of runtime past 3,000 hours, and still goes strong at 5,000 hours. Mr. Balcom said, “PolyFuel is currently working with many of the world’s largest consumer electronics and battery manufacturers, and we are pleased to see steady progress being made in commercializing portable fuel cells for consumer use.”
