The invention relates to an anode for a high-temperature fuel cell having an anode substrate andor a functional anode layer, comprising a porous ceramic structure having a first predominantly electron-conducting phase with the general empirical formula Sr1-xLnxTiO3 wherein Ln=Y, Gd to Lu and 0. The system comprises one or more articles of commerce provided for physical presentation to a customer in a first showroom. The mean value of all players’ ratings indicating their strength in the competitive game is brought closer to the reference value. Likewise all buttons, pads, keys and knobs are associated with a LED light somewhere within the controller.
