摘要： A single cell for a fuel cell stack is provided, having a membrane electrode assembly arranged in an active region, being associated with at least one single plate, which is formed with a flow field to supply an operating medium to the active region of the membrane electrode assembly, which is fluidically connected to a media port present on the side away from the active region. Lateral with respect to the membrane electrode assembly there is a lamella at least partly covering the flow cross section of the media port, which is formed to be elastically bendable by the force of a reaction medium flowing axially through the media port in order to change the useful flow cross section of the media port. A fuel cell stack having a plurality of such single cells is also provided.

摘要： An integrated fuel cell and combustor assembly includes a combustor that is fluidly coupled with at least one upstream compressor that generates compressed air. A fuel cell stack having a cathode and an anode is fluidly coupled to the combustor. The fuel cell stack is configured to receive intake fuel and a portion of the compressed air as intake air, to generate a fuel cell power output using the intake fuel and the intake air, and to direct a fuel and air exhaust from the fuel cell stack into the combustor. A self-reliant air supply system is fluidly coupled with the at least one upstream compressor and the fuel cell stack, and is configured to supply the intake air to the fuel cell stack. A fault-tolerant controller is configured to detect a transient event within the combustor and to control the self-reliant air supply system during the transient event.

摘要： The invention relates to a single corrugated fuel cell and a cell stack. The single cell comprises an anode plate, a cathode plate, and a membrane electrode assembly; the anode plate is of a corrugated structure and a plurality of anode channels and anode ribs are arranged on the anode plate in parallel; the cathode plate is of a corrugated structure engaged with the anode plate and a plurality of cathode channels and cathode ribs are arranged on the cathode plate in parallel; the membrane electrode assembly is arranged between the anode plate and the cathode plate. The single cell presents a corrugated structure in a width direction of the channel. A plurality of single cells are stacked in sequence to form a fuel cell stack. Compared with the prior art, the invention significantly increases the reaction area per unit volume of the fuel cell through the corrugated structural design, thereby improving the power density of the fuel cell. In addition, the present invention has little change to the existing processing and manufacturing technology, and thus has high production feasibility.

摘要： A fuel cell system includes a fuel cell generating electric power by a reaction between a fuel gas and an oxidant gas, an injector supplying the fuel gas to the fuel cell, a discharge line in which an off-gas discharged from the fuel cell flows, an ejector recirculating the off-gas flowing in the discharge line to the fuel cell using a flow of the fuel gas from the injector, a discharge valve discharging the off-gas flowing in the discharge line to the outside, and a control device controlling supply of the fuel gas by the injector and opening and closing of the discharge valve. When supply of the fuel gas by the injector is stopped, the control device opens the discharge valve while the off-gas is recirculated to the fuel cell and closes the discharge valve before supply of the fuel gas by the injector is restarted.

The reforming subsystem is to receive fuel and to reform fuel to generate a hydrogen enriched gases and steam mixture. The hybrid fuel cell system includes a water supply system that provides water for the steam generator. The water supply system includes a water condenser directly downstream from the reforming subsystem that is in fluid communication with the hydrogen enriched gases and steam mixture to condense the hydrogen enriched gases and steam mixture into water and hydrogen enriched gases. The depressurization system is to reduce a pressure of the hydrogen enriched gases.
