A small scale ceramic fuel cell system to which fuel gas is supplied through an injector which draws ambient air into the system. The air/fuel gas mixture is passed through a catalytic oxidation device which is thereby heated and heats a fuel cell. Air and fuel gas react at the fuel cell to generate an electrical output.

1. An electrical power source comprising a fuel cell and a first catalytic oxidation device located adjacent each other within a thermally insulating jacket such that heating of the first catalytic oxidation device results in heating of the fuel cell, means defining a gas flow passageway in which the first catalytic oxidation device and the fuel cell are connected in series, means for delivering a mixture of air and a fuel gas to the passageway such that the first catalytic oxidation device is heated by oxidation of the fuel gas and resultant oxygen-depleted gas is delivered directly to the fuel cell, and means for generating an electrical output as a result of combustion of the fuel gas in the fuel cell,wherein a fuel gas supply is connected to an injector arranged to draw ambient air into a conduit connected to the gas flow passageway, the air and fuel gas being mixed in the conduit.
