Abstract
A method of production and apparatus for a fuel cell having three nested truncated cones. The inner cone is made of a porous metal sponge, such as nickel, and provides a media through which fuel can pass. The second cone is provided around the inner cone in use, and acts as a diffuser for the fuel to promote efficient contact with the third cone. The third cone is the fuel cell itself and includes an electrolyte component which provides a gas impermeable layer between fuel and oxidation sides of the cell. A cathode and anode are provided on outer and inner surfaces respectively of the electrolyte component. The fuel cell is configured such that the lower surface of the fuel cell has a cross-sectional profile of greater area than the top surface. The top surface has an aperture allowing fuel to exit the diffuser cone.
