Ni-YSZ cermet is used as the anode of a solid oxide fuel cell (SOFC) because it has excellent electrochemical performance in both hydrogen fuel and clean blended synthetic coal syngas mixtures (e.g. 30% H2, 26% H2O, 23% CO, and 21% CO2). However, trace impurities, such as phosphine (PH3), in coal-derived syngas can cause degradation of cell performance because, for instance, Ni5P2 is formed on the cell surface. Figure 3307a shows the solid solubility of some impurities (including H) in silicon.

Figure 3307b shows the solid solubility of various impurities (including H) in germanium.
