Power supply system, fuel pack constituting the system, and device driven by power generator and power supply system
First Claim
1. A by-product elimination device used in a power generation system, comprising at least any one of:
- (a) a fuel pack provided with a fuel charged portion having a power generation fuel having a liquid or gas containing hydrogen charged therein; and
(b) a power generation module which can be attached to or detached from said fuel pack, the module including a reforming portion which transforms said power generation fuel supplied from said fuel charged portion into first gas containing hydrogen gas and carbon dioxide as main components, and a fuel cell which generates an electrical energy by using the hydrogen gas contained in said first gas, said by-product elimination device further comprising an absorbent charged portion which selectively absorbs carbon dioxide contained in said first gas fed from said reforming portion and feeds second gas whose carbon dioxide concentration is lowered by said first gas to said fuel cell.

Abstract
A by-product elimination device used in a power generation system includes a fuel pack provided with a fuel charged portion having a power generation fluid fuel containing hydrogen, and a power generation module which detachably attached to the fuel pack, the module including a reforming portion which transforms the power generation fuel supplied from the charged portion into first gas containing hydrogen gas and carbon dioxide, and a fuel cell which generates an electrical energy by using the hydrogen gas. The device includes an absorbent charged portion which selectively absorbs carbon dioxide contained in the first gas and feeds second gas whose carbon dioxide concentration is lowered by the first gas to the fuel cell.

19. A fuel pack which can be connected to a power generation module without restraint, comprising:
-
a fuel charged portion which contains a fuel to be supplied to a reforming portion which generates hydrogen and carbon dioxide from said fuel, and whose volumetric capacity is reduced as carbon dioxide is generated in said reforming portion; and
a carbon dioxide absorption portion which absorbs carbon dioxide generated by said reforming portion and whose volumetric capacity is increased as carbon dioxide is generated in said reforming portion.

20. A fuel pack which can be connected to a power generation module without restraint, comprising:
-
a fuel charged portion which contains a fuel to be supplied to a reforming portion which generates mixed gas containing hydrogen and a first by-product from said fuel, and whose volumetric capacity is reduced as said first by-product is generated in said reforming portion;
a first by-product absorption portion which generates a second by-product by absorbing said first by-product from said mixed gas, and whose volumetric capacity is increased as said first by-product is generated in said reforming portion; and
a second by-product absorption portion which absorbs said second by-product in a mixture including said hydrogen and said second by-product fed from said first by-product absorption portion. - View Dependent Claims (21, 22)

23. A fuel pack which can be connected to a power generation module without restraint, comprising:
-
a fuel charged portion which contains a fuel to be supplied to a reforming portion which generates mixed gas including hydrogen and a first by-product from said fuel, and whose volumetric capacity is reduced as said first by-product is generated in said reforming portion;
a first by-product absorption portion which absorbs said first by-product from said mixed gas, and whose volumetric capacity is increased as said first by-product is generated in said reforming portion; and
a second by-product absorption portion which collects a second by-product from a fuel cell which generates power by using said hydrogen fed from said first by-product absorption portion, and whose volumetric capacity is increased as power is generated in said fuel cell.
