An epitaxial SiC single crystal substrate including a SiC single crystal wafer whose main surface is a c-plane or a surface that inclines a c-plane with an angle of inclination that is more than 0 degree but less than 10 degrees, and SiC epitaxial film that is formed on the main surface of the SiC single crystal wafer, wherein the dislocation array density of threading edge dislocation arrays that are formed in the SiC epitaxial film is 10 arrays/cm


A system for treating a selenium-containing liquid, a wet flue gas desulfurization device, and a method for treating a selenium-containing liquid treat a selenium-containing liquid by adding bivalent manganese to the selenium-containing liquid, thereby suppressing oxidation of tetravalent selenium to hexavalent selenium. The system includes: a potential measurement unit for measuring an oxidation-reduction potential of the selenium-containing liquid, and a pH measurement unit for measuring a pH value of the selenium-containing liquid; a detection unit for detecting whether or not the selenium-containing liquid is in a state where selenium stabilizes at a valence of 4 or higher, based on the measured oxidation-reduction potential and the measured pH value; and an addition unit for adding bivalent manganese into the selenium-containing liquid when the selenium-containing liquid is in a state where selenium stabilizes at a valence of 4 or higher.

A molten carbonate fuel cell, which makes a separator unnecessary, cuts down the number of components, and markedly reduces the costs, is provided. In the cell, a cathode, an electrolyte plate holding an electrolyte, and an anode are provided concentrically with a tube body, the electrolyte plate is held by the anode, and the electrolyte plate is sandwiched between the anode and the cathode, so that the cell is constructed without the use of a separator.
