The high-profile roll-out of the highly secretive Bloom Box fuel cellElectrochemical device in which electricity is generated by chemically reacting hydrogen with oxygen; electricity, water vapor, and heat are the only products. Unlike a battery, which stores a limited fuel supply used to create electricity, a fuel cell draws on an ongoing supply of fuel to produce electricity continuously., on CBS’s 60 Minutes in February, ushered in a new round of excitement about fuel cells.
Fuel cells have been around for over 50 years. They are, in essence, chemical batteries that churn out electricity as long as a fuel, such as hydrogen or natural gas, is fed in at the other end. They have been a mainstay of power generation in NASA’s space program for decades and have slowly been making inroads for more earthly applications.
