Abstract:
A method of manufacturing a supported plurality of electrochemical extruded membranes, the method comprising:providing a first mixture comprising at a first temperature and a second mixture at a second temperature;extruding the first mixture to form a plurality of spaced-apart supportable membranes;cooling the extruded membrane from the first temperature to a third temperature;forming sufficient bubble surfaces of the second mixture between the membranes to facilitate the support of the membranes;cooling the extruded membranes and the formed bubble surfaces to a semi-solid from the second temperature to the third temperature less than the first and second temperatures;heating the cooled extruded membranes and the cooled formed bubble surfaces from the semi-solid at the third temperature to an elevated temperature sufficient to make the extruded membranes and the formed bubble surfaces into a sintered ceramic; andsufficiently cooling the extruded membranes and the formed bubble surfaces in the sintered ceramic to cause the bubbles to support the membranes.
