Features of fuel cell The distributed fuel cell demonstration power station uses natural gas as fuel. The natural gas is first converted into hydrogen, which is then sent to the fuel cell generator set to produce electricity and hot water. In principle, as long as the fuel cell continuously inputs reactants and discharges reaction products, […]
Read MoreA fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy. In 1839, British scientist W.R.Grove discovered and verified the phenomenon of fuel cells in the laboratory. However, due to the failure of the research on the dynamics of generators and electrode processes to keep […]
Read MoreAccording to the different ways of concentrating solar energy, solar thermal power generation systems can be divided into three types, namely trough solar thermal power generation systems, tower solar thermal power generation systems and dish solar thermal power generation systems. (1) Trough solar thermal power generation system. Trough solar thermal power generation system uses trough-shaped parabolic […]
Read MoreGenerally speaking, solar thermal power generation technology refers to solar steam thermal power generation technology. It uses a large-scale array of parabolic or dish-shaped mirrors to collect solar thermal energy, provides steam through a heat exchange device, and combines the technology of traditional steam turbine generators to achieve the purpose of generating electricity. It avoids […]
Read MoreThe design of solar photovoltaic power generation system is mainly divided into two parts: one is the design of photovoltaic power generation system capacity, which mainly designs and calculates the capacity and quantity of solar cell arrays and storage batteries to meet electricity demand and work reliably; the second is the configuration and design of the […]
Read MoreThe key technologies in the photovoltaic power generation system mainly include the maximum power point tracking control technology, the detection and prevention of the islanding effect, and the low voltage ride through function. 1. Maximum power point tracking control technology Because the volt-ampere characteristics of solar cells have strong nonlinearity, their output voltage and current […]

Read MoreSolar photovoltaic power generation system classification Solar photovoltaic power generation systems can be divided into off-grid (independent) photovoltaic power generation systems and grid-connected photovoltaic power generation systems. Figure 1 shows a schematic diagram of the working principle of an off-grid photovoltaic power generation system. The solar panel converts the light energy of sunlight into electric […]
Read MoreClassification of solar cells Solar cells are mainly divided into crystalline silicon solar cells and thin-film solar cells. Crystalline silicon solar cells are further divided into monocrystalline silicon solar cells and polycrystalline silicon solar cells. There are many types of thin-film solar cells, mainly amorphous silicon solar cells. The monocrystalline silicon solar cell material has […]
