A system and method of generating electrical energy using a fuel cell while decarbonizing an exhaust gas generated by the fuel cell is disclosed. Heat generated by an electrochemical reaction within the fuel cell can be recovered at both an anode side and a cathode side of the fuel cell, and at least some of the recovered heat can be used to preheat each of a fuel feed and an oxidant supplied to the fuel cell. A carbon capture system may be included and used to capture and liquefy carbon dioxide present in an anodic exhaust gas emitted by the fuel cell. At least a liquefaction subsystem of the carbon capture system may receive a cooled refrigerant from a vapor absorption and refrigeration device that cools the refrigerant using heat extracted from heat transfer fluid heated by recovered heat from the anodic exhaust gas and a cathodic exhaust gas.

The invention discloses a gap steam absorption device of a crystallizer cover plate, and belongs to the technical field of crystallizers, the gap steam absorption device comprises a gas collecting hood arranged above the crystallizer cover plate in a covering mode and a flow guide assembly communicated with the gas collecting hood, the gas collecting hood covers a gap between the crystallizer cover plate and adjacent equipment, and the flow guide assembly is communicated with the gas collecting hood. The flow guide assembly is provided with a negative pressure connector, a regulating valve and a negative pressure air draft system in a communicating mode. The device is simple in structure and convenient to disassemble and assemble, steam at a gap between a crystallizer cover plate and adjacent equipment is actively extracted by connecting an external negative pressure air draft system, and the problems that a traditional passive sealing mode is prone to aging and failure and poor in sealing effect are fundamentally solved by adopting an active absorption mode; the steam collecting and sealing effects are far better than those of a traditional sealing method, and steam can be stably prevented from overflowing for a long time.
