A gearbox includes a sun gear, a plurality of planet gears, an annulus gear and a planet carrier. The planet carrier includes a first ring, second ring spaced axially from the first ring, a plurality of circumferentially spaced axles and a plurality of circumferentially spaced support structures extending axially between and secured to the first ring and second ring. Each planet gear is rotatably mounted on a respective one of the axles. The first ring has a plurality of circumferentially spaced recesses and the second ring has a plurality of circumferentially spaced recesses. Each recess in the second ring is aligned with a corresponding one of the recesses in the first ring. A first end of each support structure locates in a recess in the first ring. A second end of each support structure locates in a recess in the second ring. Each support structure comprises a fused powdered material.

A method of manufacturing a fuel cell, more particularly a method of manufacturing a ceramic fuel cell and in particular a method of manufacturing a solid oxide fuel cell, is described herein. The method includes forming at least one sheet of electrolyte material, depositing anode electrode and cathode material on the electrolyte material, forming apertures through the electrolyte material, arranging the electrolyte material in a stack, dividing the electrolyte material into pieces, depositing additional electrode material on the surfaces of the pieces, and depositing additional electrode material on the surface of the apertures of the pieces in order to form a fuel cell.

Fuel cell and a method of manufacturing a fuel cell

A solid oxide fuel cell comprises a porous anode electrode, a dense non-porous electrolyte and a porous cathode electrode. The anode electrode comprises a first member and a plurality of parallel plate members extending from the first member. The cathode electrode comprises a second member and a plurality of parallel plate members extending from the second member. The plate members of the cathode electrode inter-digitate with the plate members of the anode electrode and the electrolyte fills the spaces between the first and second members and the parallel plate members of the anode electrode and the cathode electrode.
