Abstract
A cogeneration system using a fuel cell includes a gas-mixture-supply passage L supplied with a fuel gas and an oxidant gas; a gas combustor 31 for combusting the gas mixture which has passed through the gas-mixture-supply passage L; a combustion chamber 3 for housing the gas combustor 31; and a power generator 2 disposed on the gas-mixture-supply passage L and having at least one fuel cell that generates power from the gas mixture flowing through the supply passage L. The power generator 2 is located in the combustion chamber 3, so as to be heated by the heat of combustion produced in the combustion chamber 3.
Claims45
A cogeneration system using a fuel cell, comprising:
- a gas-mixture-supply passage supplied with a gas mixture of a fuel gas and an oxidant gas;
- a power generator disposed on the gas-mixture-supply passage and having at least one fuel cell that generates power using the gas mixture flowing through the gas-mixture-supply passage;
- a gas combustor for combusting the gas mixture which has passed through the power generator disposed on the gas-mixture-supply passage;
- and
- a combustion chamber for housing the gas combustor;
- wherein a portion of the gas-mixture-supply passage in which the power generator is disposed is located in the combustion chamber, and
- heat of combustion is produced in the combustion chamber by the gas combustor, and the power generator is heated by the heat of combustion.
A cogeneration system using a fuel cell, comprising:
- a gas-supply passage that separately supplies a fuel gas and an oxidant gas;
- a power generator disposed on the gas-supply passage and having a fuel cell that generates power when separately supplied with the fuel gas and oxidant gas;
- a gas mixer for mixing the fuel gas and oxidant gas which have passed through the power generator disposed on the gas-supply passage;
- and
- a combustion chamber having a gas combustor for combusting the gas mixture mixed by the gas mixer;
- wherein the power generator is located in the combustion chamber, so as to be heated by the heat of combustion produced in the combustion chamber.
A cogeneration system using a fuel cell, comprising:
- a power generator having a fuel cell that generates power when supplied with a fuel gas and an oxidant gas;
- and
- a combustion chamber having a gas combustor for combusting exhaust gases from the power generator;
- wherein at least one of the fuel gas and oxidant gas is preheated by part of the heat of combustion produced from the gas combustor, and
- wherein at least either a fuel-gas-supply passage or an oxidant gas-supply passage for supplying the fuel gas or oxidant gas, respectively, to the power generator, passes through the combustion chamber, whereby at least either the fuel gas or the oxidant gas is preheated by part of the heat of combustion generated from the gas combustor.
A cogeneration system using a fuel cell, comprising:
- a combustion chamber having a gas combustor in which combustion takes place when supplied with an inflammable fuel and an oxidant gas;
- and
- a power generator having a fuel cell that generates power when supplied with a combustion product containing a hydrocarbon gas discharged from the gas combustor by combustion.
