Abstract
An anode structure for incorporation into a fuel cell includes a first region having one or more electrocatalysts, in which the first region is adjacent to the fuel inlet when the anode structure is incorporated into a fuel cell, and a second region having one or more electrocatalysts, in which the second region is adjacent to the fuel outlet when the anode structure is incorporated into a fuel cell. The first region is better at promoting the electrochemical oxidation of carbon monoxide than the second region.
