Researchers at Virginia Tech
have successfully created a sugar-powered fuel cell that has an energy
storage density of 596 amp-hours per kilo — or “one order of magnitude”
higher than lithium-ion batteries. This fuel cell is refillable with a
solution of maltodextrin, and its only by products are electricity and
water. The chief researcher, Dr. Zhang, says the tech could be
commercialized in as soon as three years.
