Title:
COMPRESSOR, AIR COMPRESSOR COMPRISING COMPRESSOR, AND FUEL CELL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/151574
Kind Code:
A1
Abstract:
A compressor, an air compressor comprising the compressor, and a fuel cell device. The fuel cell device comprises a fuel cell stack (5), a motor (3), a compressor (1), and a turbo expander (2). The motor (3) is configured to drive the compressor (1) and the turbo expander (2); an air outlet of the compressor (1) is connected to the fuel cell stack (5), and an air inlet of the turbo expander (2) is connected to the fuel cell stack (5); the compressor (1) comprises a first connection mechanism (12); the turbo expander (2) comprises a second connection mechanism (22); the first connection mechanism (12) is connected to the second connection mechanism (22). A control valve (4) is further comprised, and the control valve (4) is provided at a position where the first connection mechanism (12) is connected to the second connection mechanism (22); the control valve (4) is configured to control communication between the first connection mechanism (12) and the second connection mechanism (22). Hence, the compressor can use a large-diameter pressing wheel, and can also achieve the effect of eliminating surge.
