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： The present disclosure is directed towards flow structures in electrochemical cells for use in high differential pressure operations. The flow structure on the low pressure-side of the cell has a larger surface area than the flow structure on the high-pressure side of the cell at the flow structure—MEA interface. The boundary of the high pressure flow structure is entirely within the boundary of the low pressure flow structure. A seal around the high pressure flow structure is also contained within the boundary of the low pressure flow structure. In such an arrangement, high fluid pressures acting on the electrolyte membrane from the high-pressure side of the cell is fully and continuously balanced by the flow structure on the low pressure-side of the membrane. Use of the low pressure flow structure as a membrane support prevents the rupture or deformation of the membrane under high stresses.
