초록 ▼

An improved electrochemically active system and method including a plurality of electrochemical devices, such as fuel cells and fluid separation devices, in which the anode and cathode process-fluid flow chambers are connected in fluid-flow arrangements so that the operating parameters of each of said plurality of electrochemical devices which are dependent upon process-fluid parameters may be individually controlled to provide improved operating efficiency. The improvements in operation include improved power efficiency and improved fuel utilization in fuel cell power generating systems and reduced power consumption in fluid separation devices and the like through interstage process fluid parameter control for series networked electrochemical devices. The improved networking method includes recycling of various process flows to enhance the overall control scheme.

An electrochemically active system, comprising: a plurality of electrochemical devices each having an ionically conductive membrane, a porous anode disposed in contact with said ionically conductive membrane on one side thereof, a porous cathode disposed in contact with said ionically conductive membrane on a side thereof opposite said one side of said ionically conductive membrane, an anode process-fluid flow chamber disposed in fluid communication with said anode on a surface thereof opposite the surface contacting said ionically conductive membrane, and a cathode process-fluid flow chamber disposed in fluid communication with said cathode on a surface thereof opposite the surface contacting said electrochemical membrane; means for electrically connecting said plurality of electrochemical devices in series; a cathode process-fluid communicating means for connecting said cathode process-fluid flow chambers of each of said plurality of electrochemical devices in a serial fluid-flow arrangement through each of said plurality of electrochemical devices; an anode process fluid communicating means for connecting said anode process-fluid flow chambers of each of said plurality of electrochemical devices in a serial fluid-flow arrangement so that said plurality of electrochemical devices are connected in a networked serial flow arrangement; and control means coupled with said anode and cathode process-fluid communicating means for separately controlling the process-fluid parameters of each of said plurality of electrochemical devices individually so that the operating efficiency of each of said plurality of electrochemical devices is improved, thereby improving the system efficiency. A method for operating a networked plurality of electrochemically active devices wherein each of said devices includes an ionically conductive membrane, a porous anode disposed in contact with said ionically conductive membrane on one side thereof, a porous cathode disposed in contact with said ionically conductive membrane on a side thereof opposite said one side of said ionically conductive membrane, an anode process-fluid flow chamber disposed in fluid communication with said anode on a surface thereof opposite the surface contacting said ionically conductive membrane, and a cathode process-fluid flow chamber disposed in fluid communication with said cathode on a surface thereof opposite the surface contacting said electrochemical membrane and means for electrically connecting said plurality of electrochemically active devices in series, comprising the steps of: flowing a cathode process-fluid through each of said cathode process-fluid flow chambers of each of said plurality of electrochemical devices in a serial fluid-flow arrangement; flowing an anode process-fluid through said anode process-fluid flow chambers of each of said plurality of electrochemical devices in a serial fluid-flow arrangement so that said plurality of electrochemical devices are networked in a serial process flow arrangement; and separately controlling the process-fluid parameters of each of said plurality of electrochemical devices individually so that the operating efficiency dependent on process fluid parameters of each of said plurality of electrochemical devices is improved, thereby improving the system efficiency.
