摘要:
A device or system for operating one or more electrochemical cells, such as a rechargeable fuel cell, is provided. A plurality of subsystems include a humidity level control subsystem, a reagent gas delivery subsystem, and a gas scrubbing subsystem. A method for operating the device or system is also provided.
摘要:
A method of manufacturing a fuel cell stack is provided. The method provides forming an inspectable preassembly of multiple fuel cell assemblies that may be termed a pseudostack. Each fuel cell in the pseudostack has permanent electrical interconnections and sealing connections on only one of the two electrodes, namely an anode layer or a cathode layer. For example, an anode interconnect may be firmly attached to the anode layer by means of a bonding agent and a sealing agent used to seal passages on the anode layer of the fuel cell. Alternatively, seals and permanent electrical connections may be made on the cathode layer of the fuel cell, and not on the anode layer.

An electrochemical cell includes an anode connectable to a current tap and a charging medium in electrical contact with the anode. A switching device is configured to stop a charging operation of the electrochemical cell upon activation by the charging medium.
摘要:
A desalination system wherein a latent heat of condensation produced by the temperature gradient across a membrane distillation (MD) module is transferred directly to a latent heat of vaporization during desalination of a liquid flow stream. The desalination system comprises the MD module disposed within an object and configured to receive an input feed stream for desalination and produce an output flow stream of a product. The system also comprises a vapor compressor in fluidic communication with the MD module and configured to introduce a hot steam to a high temperature side of the MD module and extract a cool steam, having a temperature less than the hot steam, from a low temperature side of the MD module, thereby creating a temperature gradient across of the MD module. A desalination method is also presented.

A combined cycle power plant includes a gas turbine, a condensing stage, a steam turbine, and a heat recovery steam generator (HRSG). The HRSG is configured to generate steam for driving the steam turbine in response to heat transferred from exhaust gas received from the gas turbine at a first temperature and to transmit the exhaust gas to the condensing turbine at a second temperature that is lower than the first temperature.
