History
During previous investigations, researchers dismissed formic acid as a practical fuel because of the high overpotential shown by experiments: this meant the reaction appeared to be too difficult to be practical. However, in 2005- 2006, other researchers (in particular Richard Masel's group at the University of Illinois at Urbana-Champaign) found that the reason for the low performance was the usage of platinum as a catalyst, as it is common in most other types of fuel cells: using palladium instead, they claim to have obtained better performance than equivalent direct methanol fuel cells. Tekion holds the exclusive license to formic-acid fuel cell technology from the University of Illinois at Urbana-Champaign. The company now is focusing on developing a miniature hybrid battery/fuel-cell unit called the Formira Power Pack and hopes to introduce the packs in the fourth quarter of 2007. The Power Packs rely on the fuel cell, instead of a conventional electrical source like a wall outlet, to recharge the batteries. When the fuel is exhausted, users simply replace the empty fuel cartridge with a fresh one. Because of the high power density of the fuel cell, it should provide about double the time between charges. This technology is expected to only cost about 10-15% more than traditional batteries.

Famous quotes containing the word history:
“The steps toward the emancipation of women are first intellectual, then industrial, lastly legal and political. Great strides in the first two of these stages already have been made of millions of women who do not yet perceive that it is surely carrying them towards the last.”
—Ellen Battelle Dietrick, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
