Abstract: There is provided a fuel cell cathode electrode, comprising a porous skeletal medium, the surface of which medium is modified or otherwise arranged or constructed to induce enhanced activated behaviour, wherein the enhanced activated behaviour is induced by means of increasing the surface area for a given volume of the electrode and/or by increasing the number and/or availability of reactive sites on the electrode. A fuel cell having such a cathode electrode, a method of manufacturing such a cathode electrode, and use of such a cathode electrode in a fuel cell is also disclosed.

Abstract: A system, method and article for ranking a gaming session between a plurality of independent player game components. A method includes receiving one or more gaming session metrics determined at each of a group of the game components participating in a gaming session; calculating a quality metric for the gaming session based on the one or more gaming session metrics received from the group of game components; and storing the quality metric for ranking the gaming session.

Abstract: Method, article and apparatus for executing computer games, and in particular, computer-based racing games. In a racing game, a player may be allowed to earn one or more game play options which may be exercised during the race. The game play options, when exercised, may modify the predefined race path to create an advantage for the player or a disadvantage to the competitors.

Abstract: System, method and article for modifying graphical objects in a gaming environment based on performance metrics. The appearance and/or performance of a vehicle, avatar or other graphical object automatically changes depending on player performance, without the need for a user to make a manual selection.
