Sphagnum fuscum hummocks. Known occurrence of "Sphagnum fuscus" are on the map above. The moss inhabits boreal forests and marshlands primarily, and is more likely to be found in colder climates. The moss is also capable of inhabiting areas of relatively high elevation. In recent studies performed in Eastern Europe, it was found that stable carbon and oxygen isotope ratios in α-cellulose of "Sphagnum fuscum" stems subsampled from hummocks and peat plateau profiles are useful indicators for summer temperature and winter precipitation at decadal to millennial timescales. In another study conducted in Alberta, Canada, it was found that "S. fuscum" serves as
Direct carbon fuel cell Direct carbon fuel cell A Direct Carbon Fuel Cell (DCFC) is a fuel cell that uses a carbon rich material as a fuel such as bio-mass or coal. The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. It also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs), and DC-SOFC. The total reaction of the cell is C + O → CO. The process in half cell notation: Despite this release of carbon dioxide, the direct carbon fuel cell is more environmentally friendly than traditional carbon burning techniques.
