Claim:
1. A method of manufacturing an electrolyte impregnated electrode for a fuel cell, the method comprising: forming a powder bed from a predetermined powder; sintering the powder bed at a first predetermined temperature to form an electrode; distributing an electrolyte powder on a surface of the electrode formed in the sintering step; and impregnating the electrode with electrolyte by heating the electrode with the electrolyte powder thereon to a second predetermined temperature while applying pressure to the electrode with the electrolyte powder thereon so as to melt and wick the electrolyte into the electrode, thereby forming the electrolyte impregnated electrode for the fuel cell; wherein at least one of the sintering and impregnating is performed by applying induction heating to at least one of the powder bed and the electrode, the induction heating is applied by an induction heating system including at least one coil and at least one susceptor, the at least one susceptor supports the at least one of the powder bed and the electrode and conducts heat to the at least one of the powder bed and the electrode, and the at least one coil comprises one of a multi-turn coil with an oval cross-section or a pair of flat coils.
