Optimization of dry reforming of methane over Ni/YSZ anodes for solid oxide fuel cells

219Outlet gas mixture composition (steam content is not shown) at 800 °C for an inlet methane flow rate (CH4,i) of 6 ml min−1 over 280 mg of NiO/YSZ anode (reduced before the test) and chemical equilibrium composition (components are indicated with the suffix “,eq”) calculated at 800 °C (steam and solid carbon contents are omitted) varying the inlet carbon dioxide-methane molar ratio (CO2,i/CH4,i). On the y-axis the concentration of the species is normalized, dividing the volumetric flow rates by the inlet methane flow rate (CH4,i).
