Abstract
High power density generators are formed with a flexible multi-layered structure. The structure includes a fuel layer with a separate fuel cell stack adjacent to each side of the fuel layer. The structure can be flexible and formed into a variety of shapes.
Claims24
A power generator comprising:
- at least one multi-layer structure having a flexible layer of solid fuel, the layer having first and second spaced apart sides and a thickness substantially less than one of a length or a width thereof and wherein the solid fuel of the flexible layer is substantially continuous between opposing spaced apart sides and across the thickness;
- and
- first and second flexible fuel cell layers, positioned on respective sides of and in direct contact with the opposing respective sides of the fuel layer, the fuel cell layers each having a thickness parameter substantially less than one of an electrode length, or an electrode width thereof, the structure having a fuel cell area that generates electrical energy with a power density in excess of 10 watts/liter.
A power generator comprising:
- at least one multi-layer fuel cell, the fuel cell incorporating an anode and a cathode spaced apart at least by a solid electrolyte;
- and a layer of solid fuel positioned adjacent to the multi-layer fuel cell with the combined multi-layer fuel cell and fuel layer having a fuel cell area that generates electrical energy with a power density in excess of 10 watts/liter wherein the solid fuel of the layer is substantially continuous in length, width and thickness and wherein the anode and cathode are in direct contact with opposing sides of the layer of solid fuel.
A method comprising:
- providing a flexible layer of solid fuel, the solid fuel of the flexible layer being substantially continuous in length, width and thickness;
- providing flexible first and second layers of fuel cells;
- interconnecting the respective cells in accordance with a predetermined configuration;
- and
- positioning the layers of cells with the fuel layer therebetween with each of the layers of cells in direct contact with the fuel layer thereby &timing a multi layer electrical generator.
