The present invention provides, among other things, a method of operating a solid oxide fuel cell system including a fuel cell stack. The method can include the acts of combining an exhaust flow from an anode side of the fuel cell stack and an exhaust flow from a cathode side of the fuel cell stack, transferring heat from the combined exhaust flow to a first air flow, and combining a second air flow and the heated first air flow upstream from the fuel cell stack to control a temperature of the combined air flow entering the cathode side of the solid oxide fuel cell.

An optoelectronic arrangement having a surface-mountable semiconductor module having at least one optoelectronic transmitting and / or receiving unit, a housing, in which the optoelectronic transmitting and / or receiving unit is arranged, and a mounting side of the housing, which, in the case of surface mounting of the semiconductor module on a printed circuit board, faces the printed circuit board. The arrangement furthermore has a cooling element, which is thermally coupled to the semiconductor module for the purpose of cooling the optoelectronic transmitting and / or receiving unit. The cooling element is arranged on a side of the housing that is remote from the mounting side.

The invention provides an apparatus (for heat treating a packaged food product), comprising (a) a channel surrounding a channel interior, (b) a pressurizer, (c) a transport unit, (d) a first electrode, surrounding at least part of the channel interior over a first electrode length, (e) an electrode configuration comprising (i) a second electrode surrounding at least part of the channel interior over a remote part surrounding length (for shielding at least part of the channel), and (f) a radio frequency wave generator configured to generate RF-waves between the first and second electrode. With such apparatus efficiently energy may be coupled into the packaged food product, for instance for heating a meal and / or for pasteurizing a food product. A further advantage of the present apparatus and such process is that it may be configured to be used in a continuous process.

A thermo-driven engine includes cylinders and at least one hydraulic motor. Each cylinder contains an air chamber and a hydraulic chamber therein. A piston is disposed between both chambers. The air chamber is intermittently heated to create pressure difference in the air chamber of the cylinder to force the piston moving to the hydraulic chamber, thus to drive the hydraulic motor for continuously generating power.
