The attachment thermally conducts heat generated from an electronic component to the fuel tank. The attachment further affixes to the electronic component by a securing portion. In one aspect, the attachment is comprised in a fuel cell powered electronic device. In another aspect, the attachment is integral to the fuel tank. ## Claims ### Claim at position 1 -20. (canceled) ### Claim 21 A portable electronic device comprising: a fuel tank adapted to store fuel for a fuel cell for providing power to the portable electronic device; and an attachment adapted to affix the fuel tank in thermal conduction with at least one heat generating electronic component on the portable electronic device, the attachment including: a thermal conductor having a first surface for thermally contacting the at least one heat generating electronic component and a second surface for thermally contacting the fuel tank, the thermal conductor conducting heat generated by the at least one electronic component such that heat generated by the at least one electronic component is absorbed by the fuel tank; and a securing portion for affixing the first surface to the at least one electronic component, the securing portion comprising a lip located in opposition with the first surface such that an edge of the at least one electronic component resides between the lip and the first surface and is retained therein. ### Claim 22 (depends on 21) The device of claim 21 wherein the lip extends in a direction parallel to the first surface. ### Claim 23 (depends on 21) The device of claim 21, wherein the lip and the first surface cooperate to inhibit relative movement of the electronic component and fuel tank in a direction perpendicular to the first surface. ### Claim 24 (depends on 21) The device of claim 21, wherein a space between the lip and the first surface is sized so that the at least one electronic component fits snugly between the first surface and the lip to inhibit relative movement between the fuel tank and the at least one electronic component. ### Claim 25 (depends on 24) The device of claim 24, wherein the lip and first surface inhibit relative movement of the fuel tank and at least one electronic component in a direction perpendicular to the first surface. ### Claim 26 (depends on 24) The device of claim 24, wherein the lip and first surface create a pressure fit that inhibits relative movement of the fuel tank and at least one electronic component in a direction parallel to the first surface. ### Claim 27 (depends on 21) The device of claim 21 wherein the securing portion is adapted to reside within an aperture defined by the at least one electronic component. ### Claim 28 (depends on 27) The device of claim 27, wherein the securing portion includes an intermediate section that fits within the aperture, the intermediate section inhibiting relative lateral movement between the at least one electronic device and the fuel tank. ### Claim 29 (depends on 21) The device of claim 21 wherein the attachment is an integral part of the fuel tank. ### Claim 30 (depends on 21) The device of claim 21 wherein the first surface physically conforms to the at least one electronic component. ### Claim 31 (depends on 21) The device of claim 21 wherein the fuel tank defines an interior space for storing fuel. ### Claim 32 A fuel tank and fuel cell powered electronic system comprising: at least one heat generating electronic component; a fuel tank adapted to store fuel for a fuel cell; and an attachment adapted to affix the fuel tank in thermal conduction with the at least one heat generating electronic component, the attachment including: a thermal conductor having a first surface for thermally contacting the at least one heat generating electronic component and a second surface for thermally contacting the fuel tank, the thermal conductor conducting heat generated by the at least one electronic component such that heat generated by the at least one electronic component is absorbed by the fuel tank; and a securing portion for affixing the first surface to the at least one electronic component, the securing portion comprising a lip located in opposition with the first surface such that an edge of the at least one electronic component resides between the lip and the first surface and is retained therein. ### Claim 33 (depends on 32) The system of claim 32 wherein the lip extends in a direction parallel to the first surface. ### Claim 34 (depends on 32) The system of claim 32, wherein the lip and the first surface cooperate to inhibit relative movement of the electronic component and fuel tank in a direction perpendicular to the first surface. ### Claim 35 (depends on 32) The system of claim 32 wherein a space between the lip and the first surface is sized so that the at least one electronic component fits snugly between the first surface and the lip to inhibit relative movement between the fuel tank and the at least one electronic component. ### Claim 36 (depends on 35) The system of claim 35, wherein the lip and first surface inhibit relative movement of the fuel tank and at least one electronic component in a direction perpendicular to the first surface. ### Claim 37 (depends on 35) The system of claim 35, wherein the lip and first surface create a pressure fit that inhibits relative movement of the fuel tank and at least one electronic component in a direction parallel to the first surface. ### Claim 38 (depends on 32) The system of claim 32 wherein the securing portion is adapted to reside within an aperture defined by the at least one electronic component. ### Claim 39 (depends on 38) The system of claim 38, wherein the securing portion includes an intermediate section that fits within the aperture, the intermediate section inhibiting relative lateral movement between the at least one electronic device and the fuel tank. ### Claim 40 (depends on 32) The system of claim 32 wherein the attachment is an integral part of the fuel tank.
