Fuel cell-gas turbine-wind energy-solar energy comprehensive power generation system

Abstract

The invention discloses a fuel cell gas turbine wind energy and solar energy comprehensive power generation system which is characterized by comprising four systems, namely a fuel cell power generation system which comprises a methane supply device, a methane pre-reformer, a hydrogen-oxygen fuel cell, a transformer and a catalytic combustion chamber, wherein the hydrogen-oxygen fuel cell comprisesan anode channel, an anode, a cathode and a cathode channel; the groove type solar light-gathering and heat-collecting system comprises a groove type solar light-gathering and heat-collecting device,a rotating server and a first heat exchanger. The gas turbine power generation system comprises a starting motor, a gas compressor, a second heat exchanger, a turbine and a power generator. The winddriven generator system comprises a wind driven generator; the four systems have four energy conversion mechanisms and are interwoven and recycled, the advantages of fuel cell power generation, fuel cell and gas turbine combined power generation and comprehensive utilization of wind energy and solar energy are considered, and meanwhile the defects that the fuel utilization rate is low, and the energy utilization mode is single are overcome.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of fuel cells, gas turbines, wind energy and solar energy, and in particular relates to a fuel cell-gas turbine-wind energy-solar comprehensive power generation system. Background technique [0002] The traditional fuel utilization method is to release energy directly through combustion, and convert the chemical energy of the fuel into heat energy. The advantage of direct combustion of fuel is that the utilization method is simple and direct, and the technical requirements are not high. The disadvantage is that the fuel utilization rate is low, and a large amount of carbon dioxide and other harmful gases will be produced, causing damage to the environment. With the serious shortage of fossil energy and the sharp decline of environmental quality, how to make full use of energy has become the focus of current research. [0003] The power of traditional gas turbines relies on the combustion ...
