PURPOSE:To lessen the thermal stress applied to fuel cell element and equalize the power generating efficiency by supplying oxidated gas through an oxidated gas supply hole in No.1 power generating chamber, and by supplying the fuel gas through a fuel gas supply hole in No.2 power generating chamber. CONSTITUTION:An oxidated gas A supply hole 2a is provided approx. in the middle of No.1 power generating chamber 6A of an electroconductive oxidated gas supply pipe 2 penetrating the No.1 power generating chamber 6A, while a fuel gas B supply hole 3a is formed approx. in the middle of No.2 power generating chamber 6B of an electroconductive fuel gas supply pipe 3 penetrating this chamber 6B. Because the gases A, B exhausted from these supply holes 2a, 3a proceed radially within the chambers 6A, 6B, the passing distance from the supply holes 2a, 3a till a combusted object producing chamber 7. This lessens the heat conduction resistance between the high temp. part and low temp. part, and the temp. gradient from each gas supply hole 2a, 3a to the combusted object producing chamber 7 can be made smaller, and the thermal stress will be lessened and the power generating efficiency be equalized. |
