摘要： A solid oxide electrolyser cell system includes an electrolysis stack comprising an anode, a cathode and a solid-oxide electrolyte. The anode comprises an anode inlet. The system comprises a sweep gas supply for supplying a sweep gas to the anode via the anode inlet, and a sweep gas supply flow path defining a flow path between the sweep gas supply and the anode inlet. The system comprises a first heat exchanger in communication with the sweep gas supply flow path. The first heat exchanger communicates with a stream having a source external to the system and defining an external stream flow path. The first heat exchanger exchanges heat between the sweep gas supply flow path and the external stream flow path. An example method of operating such a system includes exchanging heat between the external stream flow path and the sweep gas supply flow path through the first heat exchanger.

摘要： An electrochemical cell assembly (300, 500) comprising a base plate (308) and a top plate (303) between which a stack of planar cell units (306) and at least one positive (302, 507) and at least one negative electrical end plate (302, 507) are disposed in compression by means of compression means (307) acting between the base plate (308) and top plate (303). At least one of the electrical end plates (302, 507) is connected or integrally formed with, and in electrical contact with, an electrical stud (301, 505) that extends from a base portion of the at least one electrical end plate (302, 507) and passes through an opening in one of the base plate (308) and top plate (303) to form an electrical terminal. A fluidic seal is maintained by the compression means (307) between the base portion and the respective one of the base plate (308) and top plate (303), so as to prevent loss of fluid through the opening.

摘要： A stack module fault detection system, comprising an insulation resistance tester; a stack module, consisting of a plurality of stacks; and a plurality of switch groups, wherein each switch group comprises a first switch and a second switch, each switch group is respectively connected with a stack, the first end of the first switch is connected with the positive electrode of the stack, and the first end of the second switch is connected with the negative electrode of the stack; the second end of the first switch is connected with the positive electrode of the insulation resistance tester, and the second end of the second switch is connected with the negative electrode of the insulation resistance tester. A controller connected with the control end of the switch group controls the opening and closing of the switch group. The insulation resistance tester detects the insulation resistance of each stack in turn and sends the insulation resistance to the controller to monitor the insulation fault in the stack module. Under the condition of not disassembling the stack module, the insulation resistance of each stack is detected, and the stack with insulation fault can be located, so that the operation of fault positioning is simplified.

摘要： A vehicle control method and device. The vehicle control method comprises the steps of generating a first control instruction and a second control instruction when a vehicle is in a parking state, so that a fuel cell control unit (FCU) is controlled to perform charging control on a battery management system (BMS) through the first control instruction, a vehicle control unit (VCU) is controlled to perform power-off control on a target component through the second control instruction, and the target component is a non-essential operation component when the vehicle is charged in a parking state; and generating a third control instruction when the vehicle is in a normal operating state, so that the VCU controls the BMS according to the third control instruction. According to the method, under different vehicle states of the BMS, the control instructions are sourced from different control units; after the vehicle enters the parking charging mode, the non-essential components are enabled to stop working to lower a parasitic load, thereby improving the charging efficiency of the system.
