Abstract
Abstract A internal reforming type molten carbonate fuel cell is provided in which the process or flow direction of the reforming reaction of a raw fuel gas in the reforming reaction section is countercurrent to the flow direction of the oxidant gas in the cell reaction section. Therefore, a temperature difference in the fuel cell can be suppressed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
95 words
An internal reforming type molten carbonate fuel cell comprising: a cell reaction section having a fuel electrode, an oxidant electrode and electrolyte . matrix interposed therebetween for generating electricity by suppying a fuel gas and an oxidant gas to said fuel electrode and said oxidant electrode, respectively; and a reforming reaction section for reforming a raw fuel gas to said fuel gas, wherein the process direction of the reforming reaction of said raw fuel gas in said reforming reaction section is countercurrent to the flow direction of said oxidant gas in said cell reaction section.
Claim 2
Dependent Claim
95 words
An internal reforming type molten carbonate fuel cell comprising: a cell reaction section having a fuel electrode, an oxidant electrode and electrolyte . matrix interposed therebetween for generating electricity by suppying a fuel gas and an oxidant gas to said fuel electrode and said oxidant electrode, respectively; and a reforming reaction section for reforming a raw fuel gas to said fuel gas, wherein the process direction of the reforming reaction of said raw fuel gas in said reforming reaction section is countercurrent to the flow direction of said oxidant gas in said cell reaction section.
Claim 3
Dependent Claim
36 words
A fuel cell as claimed in claim 1 wherein said process direction of the reforming reaction of said raw fuel gas is orthogonal to the flow direction of said fuel gas in said cell reaction section.
Claim 4
Dependent Claim
24 words
A fuel cell as claimed in claim 1 further comprising a gas distributing section for changing the flow derection of said raw fuel gas.
