摘要： The present disclosure is directed to a fuel cell system for generating oxygen depleted air. The fuel cell system may include a fuel cell having an anode, a cathode, and an electrolyte positioned between the anode and the cathode. The cathode may be configured to receive an air flow and discharge an oxygen depleted air flow. The fuel cell system may further include a sensor configured to generate a first signal indicative of a presence of hydrogen in the oxygen depleted air flow and a controller in communication with the sensor and the fuel cell. The controller may be configured to detect the presence of hydrogen in the oxygen depleted air flow based on the first signal, and in response to detecting the presence of hydrogen in the oxygen depleted air flow, selectively cause a current density of the fuel cell to decrease and/or increase a flow rate of the air flow to the cathode.

摘要： A pressure swing adsorption (PSA) system for purifying a feed gas is provided. The PSA system may have a first adsorber bed and a second adsorber bed, each having a feed port, a product port, and adsorbent material designed to adsorb one or more impurities from the feed gas to produce a product gas. The PSA system may also have a first valve configured to direct flows of the feed gas and the product gas through a network of piping. The PSA system may further have a first orifice configured to regulate a flow rate of gas between the first adsorber bed and the second adsorber bed during the pressure equalization step and a second orifice configured to regulate a flow rate of gas between the first adsorber bed and the second adsorber bed during the purge step.

摘要： The present disclosure is directed to steam reformers for the production of a hydrogen rich reformate, comprising a shell having a first end, a second end, and a passage extending generally between the first end and the second end of the shell, and at least one heat source disposed about the second end of the shell. The shell comprises at least one conduit member comprising at least one thermally emissive and high radiant emissivity material, at least partially disposed within the shell cavity. The shell further comprises at least one reactor module at least a portion of which is disposed within the shell cavity and about the at least one conduit member and comprises at least one reforming catalyst. The disclosure is also directed to methods of producing a hydrogen reformate utilizing the steam reformers, comprising the steps of combusting a combustible mixture in a burner to produce a combustion exhaust that interacts with the steam reactor module(s) through surface to surface radiation and convection heat transfer, and reforming a hydrocarbon fuel mixed with steam in the steam reformers to produce a hydrogen-containing reformate. The present disclosure is further directed to reactor modules for use with the above steam reformers and methods of producing a hydrogen reformate.

摘要： Embodiments of present disclosure are directed to a bipolar plate assembly. The bipolar plate assembly has a frame and a base. At least one of the frame and the base has a shape of a force concentrator pattern or has a first surface having a force concentrator pattern, the force concentrator pattern including a raised surface extending partially across the first surface. A surface area of the force concentrator pattern across the length of the frame or base is generally constant, thereby producing a uniform compressive pressure along the length of the frame or base when the bipolar plate assembly is under compression.

摘要： A bipolar plate assembly is provided. The bipolar plate assembly may have a first seal assembly including a first high pressure seal, a second high pressure seal, and an insert plate disposed between the first high pressure seal and the second high pressure seal. The insert plate may have a plurality of ridges formed on an upper surface and a lower surface of the insert plate configured to penetrate into the first high pressure seal and the second high pressure seal when the first high pressure seal and the second high pressure seal are pressed onto the insert plate, thereby forming the seal assembly. The bipolar plate assembly may also have a frame and a base configured to be joined to form a bipolar plate and define a high pressure zone. The seal assembly when installed in the bipolar plate may be configured to seal the high pressure zone.
