Definitions
- air oxygen
- the fuel cell typically supplies the oxidant supply gas to the cathode 44 from an oxidant source such as air.
- the oxidant supply gas may be air, or in some cases, may be a gas in which some of the cathode exhaust gas is recycled and mixed with air.
- an oxidant supply gas needs to be heated to an appropriate temperature in order to be supplied to the cathode 44.
- a catalytic combustor 50 which burns unreacted fuel gas in the anode exhaust gas and heats the oxidant supply gas is used. The heated oxidant supply gas is supplied to the cathode 44 of the fuel cell stack.
- molten carbonate fuel cells that produce electricity through this process produce heat as well as electricity. Therefore, in a fuel cell system using a high temperature fuel cell such as a molten carbonate fuel cell, the efficiency of the entire system depends on how the heat is used. Different. Accordingly, various methods of using such heat to improve the efficiency of the entire system are currently being devised. For example, a method of using such heat as a heating heat source has been attempted. However, in order to use this heat as a heating heat source, there is a limitation that a fuel cell system must be installed not far from where such a heating heat source is needed.
- FIG. 2 is a block diagram illustrating a fuel cell hybrid system according to another embodiment of the present invention.
- the heat engine 200 includes a compression means 210 and an expansion means 220.
- the compression means 210 is configured to receive and compress an oxidant supply gas from an oxidant source such as air.
- the compression means 210 according to the present embodiment may be a conventional compressor for compressing gas.
- the oxidant feed gas heated through the first heat exchanger 510 is further heated through the second heat exchanger 520.
- the second heat exchanger 520 exchanges the oxidant supply gas discharged from the first heat exchanger 510 and the oxidant supply gas discharged from the catalytic burner 150 to exchange the oxidant supply gas passed through the first heat exchanger 510. Heat more.
- the oxidant supply gas discharged from the catalytic combustor 150 is also the first. It has a temperature sufficient to heat the oxidant feed gas exiting the heat exchanger 510.
- the hybrid system according to the present embodiment since the heat produced by the fuel cell 100 is utilized in the heat engine 200, the efficiency of the entire system may be improved. More specifically, the hybrid system according to the present embodiment includes not only heat (see first heat exchanger) of the cathode exhaust gas exhausted from the cathode, but also heat (see second heat exchanger) of the oxidant supply gas discharged from the catalytic combustor. Since it is transferred to 200, not only the heat required by the heat engine 200 can be sufficiently secured, but also the heat from the fuel cell 100 can be utilized without waste, thereby improving the efficiency of the entire system.
- the system according to the present embodiment may further include a first control valve 531 to adjust the flow rate of the oxidant supply gas supplied from the oxidant source to the catalytic combustor 150.
- the system according to the present embodiment may further include a burner 535 to heat the oxidant supply gas supplied from the oxidant source to the catalytic combustor 150.
- the hybrid system according to the present embodiment has a second regulating valve as shown in FIG. 1 for controlling the temperature, that is, to adjust the flow rate of the oxidant supply gas supplied to the oxidant supply gas discharged from the catalytic combustor 150. 532 may be further included.
