摘要： The present disclosure generally relates to a mounting device for mounting a fan unit. The mounting device may include a reference plane and a reference axis normal to the reference plane, the fan unit in a disengaged orientation being receivable towards the reference plane along the reference axis. The device may also include a set of engagement members radially disposed around the reference axis and arranged to surround the fan unit in the disengaged orientation at the reference plane, the engagement members engageable with the fan unit upon actuation of the fan unit planarly along the reference plane from the disengaged orientation to an engaged orientation. The dice may also include a set of engagement elements disposed on the engagement members, the engagement elements engageable with a set of mounting holes of the fan unit upon actuation of the fan unit to the engaged orientation. Upon engagement with the fan unit, the engaged engagement members and engagement elements resist movement of the fan unit relative to the mounting device.

摘要： A fuel cell system and method are provided. The fuel cell system includes a fuel cell stack, a fuel water trap to store condensate generated by the fuel cell stack, and a controller. After a change in a water level of the fuel water trap, the controller determines whether the fuel cell stack is in a non-load operation state based on a first parameter indicating a ratio between a power consumption of an accessory machine and the change in the water level.

摘要： An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

摘要： Proposed is an air supply apparatus for a fuel cell. More particularly, proposed is an air supply apparatus for a fuel cell, in which a blower fan for supplying air for cooling a stack and a blower for supplying air for reaction in the fuel cell are separately provided, thereby preventing overheating of the blower through efficient operation of the blower and preventing damage to the fuel cell caused by oxygen, foreign substances, etc. being supplied to a cathode during storage of the fuel cell; and a part of air supplied through an air generating part of the blower is sprayed toward the outside of the air generating part, thereby preventing overheating of the air generating part and lowering the temperature of air supplied to the cathode.

摘要： A fuel cell system includes a hydrogen expansion system comprising an aeolipile, and a heat exchanger for receiving and expanding hydrogen received from a supply of hydrogen, for provision to the aeolipile. A generator coupled to the aeolipile may generate electrical power from operation of the aeolipile. The hydrogen leaving the aeolipile may be returned to the heat exchanger to transfer heat to the hydrogen received from the supply of hydrogen.
