A fuel cell includes a pair of separators and a plurality of electrolyte electrode assemblies between the separators. The electrolyte electrode assemblies has a small circular disk shape. Eight electrolyte electrode assemblies are arranged along an inner circle and eight electrolyte electrode assemblies are arranged along an outer circle concentric with a circular hole. Each of the separators includes a plurality of plates stacked together. A fuel gas channel for supplying a fuel gas to anodes of the electrolyte electrode assemblies, an oxygen-containing gas channel for supplying an oxygen-containing gas to cathodes of the electrolyte electrode assemblies are formed between the plates.

The invention relates to a high-speed direct current switch reluctance generator converter system. The system comprises four-phase windings, six switch tubes, seven diodes, five capacitors, an inductor and an isolation converter. Converter loops of the first phase winding and the second phase winding have simple structures and the same control modes, and a third phase winding and a fourth phase winding are asymmetrically integrated conversion structures. By depending on the relatively complex converter loops and the regulation and control of the fourth phase winding, the measure of enhancementof the power generation capacity of the fourth phase winding itself can be achieve such as a follow current stage, and the fourth phase winding can be mutually promoted with the third phase winding to indirectly improve the power generation capacity of the first phase winding and the second phase winding; and besides, the structure is high in expandability, the output end is connected in series to increase the voltage, the total excitation source of each phase winding is regulated according to the duty ratio of a sixth switch tube so that the high-speed direct current switch reluctance generator converter system is a set of high-performance conversion system, is especially suitable for the high-speed direct current switch reluctance generator application field, and can be taken as one ofthe generator in the internal direct current microgrid in a full-electric aircraft.

Disclosed is a high-voltage current conversion system of a switch reluctance wind power generator. A switch reluctance generator is used as a main wind power generator, and the output electric energyof a permanent magnet direct current generator coaxially connected with the switch reluctance generator is used as exciting electric energy of the switch reluctance generator; each phase of winding ofthe switch reluctance generator comprises two branches which are connected in parallel in excitation while in series in power generation, thereby strengthening the excitation effect; in power generation, the direct current power supply needed by excitation and a charged capacitor in excitation are both connected with the corresponding phase winding to be participated in power generation output, thereby highly improving the output voltage; and the whole current conversion system is high in expandability, high in reliability, simple in structure, easy to control, low in loss and suitable for medium-low-power wind power and medium-high-voltage direct current grid connection or direct current load power utilization fields.
