SUBJECT For portable power applications, mass marketing may be just around the corner--or a little beyond. Co. were touting their use in portable electronics. Co.'s scientist underscored the point by showing audiences that a squirt of methanol was sufficient to make his demonstration cell phone spring to life. Co.'s scientist explains that by developing miniature PEM-type cells that run directly on methanol--without first reforming the fuel to extract hydrogen--consumers will benefit from the alcohol's high energy density. Cell phones, laptop computers, and other devices could run for a long time on a small charge of methanol. Today's fuel-cell cars and generators may be more energy efficient and environmentally friendly than conventional types of those products, Co.'s scientist says, but they're expensive and don't provide better service than ordinary cars and generators. So most customers aren't inclined to spend the extra money. But when consumers benefit, they will pay.For example, when lithium-ion batteries came to market with roughly double the per-charge life of nickel-cadmium batteries, customers paid a premium for them. "Portable fuel cells can deliver more energy per unit mass than Li-ion batteries," Co.'s scientist says, "and customers are willing to pay for it." Li-ion batteries can provide roughly 100 watt-hours (Wh) per kg. Direct methanol fuel cells (DMFCs), under certain test conditions, have done better by a factor of four. And 1,000 Wh per kg is an achievable DMFC target.
