Package for a miniature fuel cell
A package for a fuel cell having an upper plate having a plurality of openings, the front surface of a cell element being intended to be received under each opening to close it, each cell element having a first pad and a second connection pad, each opening being provided with at least one crossbar connecting two sides of the opening, this crossbar having at least a conductive track portion having a first end connected to a pad of a first cell element and having a second end connected to a pad of a neighboring cell element.
1. A package for a fuel cell comprising an upper plate having a plurality of pairs of openings, each of the pair of openings receiving the front surface of a common cell element to close the pair of openings, each cell element having a first connection pad and a second connection pad, each of the pair of openings being provided with at least one crossbar connecting two sides of the pair of openings, this crossbar having at least a conductive track portion having a first end connected to a pad of a first cell element and having a second end connected to a pad of a neighboring cell element.
2. The package of claim 1 , wherein the package includes a lower plate having an access port and that mates with the upper plate to define a space therebetween that is closed to an external environment.
3. The package of claim 1 , wherein the pads and the ends of the conductive track portions are connected by a conductive glue.
4. The package of claim 1 , wherein the upper plate is formed of two wafers of a plastic material between which the conductive tracks are sandwiched.
5. A fuel cell comprising the package of claim 1 and a plurality of cell elements serially connected by said conductive tracks.
6. The fuel cell of claim 5 , wherein each cell element is glued under the corresponding opening.
7. The fuel cell of claim 5 , comprising at least one holding spacer under at least one of the cell elements.
8. A package for a fuel cell comprising:
an upper plate having a plurality of pairs of openings with a crossbar positioned between openings of each pair;
a lower plate that mates with the upper plate to define spaces within the package to hold cell elements, each of the spaces positioned beneath a corresponding pair of openings such that a cell element, when positioned in the space, will close the corresponding pair of openings; and
conductive track portions that connect, in series, cell elements associated with each of the plurality of pairs of openings, the conductive track portions extending to the cell elements through crossbars of each of the plurality of pair of openings.
9. The package of claim 8 , wherein each of the plurality of crossbars has a first pad and a second pad and each of the plurality of conductive track portions connect to a first pad of one of the plurality of crossbars and to a second pad of an adjacent one of the plurality of crossbars.
10. The package of claim 9 , wherein the plurality of conductive track portions are connected to the first and second pads with a conductive glue.
11. The package of claim 8 , wherein the lower plate includes an access port through which fuel fluid may be supplied to cell elements in the package.
12. The package of claim 8 , wherein the upper plate is formed of two wafers of a plastic material between which the plurality of conductive track portions is sandwiched.
13. A fuel cell comprising the package of claim 8 and a plurality of cell elements, each of the plurality of cell elements associated with one of the plurality of pairs of openings and connected in series by the plurality of conductive track portions.
14. The fuel cell of claim 13 , wherein each of the plurality of cell elements is glued in position under the associated pairs of openings.
15. The fuel cell of claim 13 , further comprising one or more spacers positioned between at least some of the plurality of cell elements and the lower plate.
