Abstract: A method of operating a 3-D printer apparatus includes a tank structure with a bottom wall with a printing area defined above and spaced apart from the bottom wall. A gas permeable liquid within the tank overlays the bottom wall of the tank structure defining a first mobile layer below the printing area. An inhibition liquid within the tank overlays the gas permeable liquid defining a second mobile layer below the printing area. A polymerizable resin overlays the inhibition liquid and flows into the printing area. Positioning of an object carrier controlled such that a lower surface of the object carrier is initially located within the polymerizable resin and within the printing area. Operation of a resin curing device beneath the bottom wall provides light to the printing area polymerizing predetermined portions of the polymerizable resin forming an object attached to the lower surface of the object carrier.

Abstract: A proton conduction fuel cell has an anode support made of metal having a fuel flow channel, an anode comprising an anode active material in contact with the anode support, a cathode support made of metal having a cathode gas flow channel, a cathode comprising a cathode active material in contact with the cathode support, and an electrolyte layer. The electrolyte layer comprises a first layer of electrolyte formed in a lock pattern on the anode and a second layer of the electrolyte formed in a key pattern on the cathode. The second layer fits in the lock pattern of the first layer to form the electrolyte layer.

Abstract: A 3-D printer apparatus (three-dimensional printer apparatus) includes a bottom structure of a tank. The tank defines a printing area located above and spaced apart from the bottom structure. The bottom structure includes oxygen releasing electrodes. A resin curing device is configured to selectively provide light to the printing area. The electronic controller controls operation of the resin curing device and the oxygen releasing electrodes. The electronic controller selectively operates areas of the oxygen releasing electrodes thereby releasing oxygen to predetermined locations below the printing area in order to temporarily prevent the polymerization of a polymerizable resin within predetermined locations of the printing area during the printing process.
