Definitions

  • This invention relates generally to fuel cell power plants, and more particularly to a fuel cell power plant integrated with a Rankine cycle such as an Organic Rankine cycle (ORC), and that employs an internal or external combustion engine downstream of a fuel cell anode, and that is driven by the unconverted fuel exiting the fuel cell to achieve higher total plant efficiencies than that achievable from conventional fuel cell power plants.
  • a Rankine cycle such as an Organic Rankine cycle (ORC)
  • ORC Organic Rankine cycle
  • Fuel cells are electrochemical energy conversion devices that have demonstrated a potential for relatively high efficiency and low pollution in power generation.
  • a fuel cell generally provides a direct current (DC) which may be converted to alternating current (AC) via for example, an inverter.
  • DC direct current
  • AC alternating current
  • the DC or AC voltage can be used to power motors, lights, and any number of electrical devices and systems.
  • Fuel cells may operate in stationary, semi- stationary, or portable applications. Certain fuel cells, such as solid oxide fuel cells (SOFCs), may operate in large-scale power systems that provide electricity to satisfy industrial and municipal needs. Others may be useful for smaller portable applications such as for example, powering cars.
  • SOFCs solid oxide fuel cells
  • a fuel cell produces electricity by electrochemically combining a fuel and an oxidant across an ionic conducting layer.
  • This ionic conducting layer also labeled the electrolyte of the fuel cell, may be a liquid or solid.
  • Common types of fuel cells include phosphoric acid (PAFC), molten carbonate (MCFC), proton exchange membrane (PEMFC), and solid oxide (SOFC), all generally named after their electrolytes.
  • PAFC phosphoric acid
  • MCFC molten carbonate
  • PEMFC proton exchange membrane
  • SOFC solid oxide
  • fuel cells are typically amassed in electrical series in an assembly of fuel cells to produce power at useful voltages or currents. Therefore, interconnect structures may be used to connect or couple adjacent fuel cells in series or parallel.
  • components of a fuel cell include the electrolyte and two electrodes.
  • the reactions that produce electricity generally take place at the electrodes where a catalyst is typically disposed to speed the reactions.
  • the electrodes may be constructed as channels, porous layers, and the like, to increase the surface area for the chemical reactions to occur.
  • the electrolyte carries electrically charged matter from one electrode to the other and is otherwise substantially impermeable to both fuel and oxidant.
  • the fuel cell converts hydrogen (fuel) and oxygen (oxidant) into water to produce electricity.
  • air is employed as the oxidant, the nitrogen in the air is substantially inert and typically passes through the fuel cell.
  • Hydrogen fuel may be provided via local reforming (e.g., on-site steam reforming) of carbon-based feedstocks, such as reforming of the more readily available natural gas and other hydrocarbon fuels and feedstocks.
  • hydrocarbon fuels include natural gas, methane, ethane, propane, methanol, syngas, and other hydrocarbons.
  • the reforming of hydrocarbon fuel to produce hydrogen to feed the electrochemical reaction may be incorporated with the operation of the fuel cell. Moreover, such reforming may occur internal and/or external to the fuel cell.

  • Fuel cell systems that can reform hydrocarbon internal and/or adjacent to the fuel cell may offer advantages, such as simplicity in design and operation.
  • the steam reforming reaction of hydrocarbons is typically endothermic, and therefore, internal reforming within the fuel cell or external reforming in an adjacent reformer may utilize the heat generated by the typically exothermic electrochemical reactions of the fuel cell.
  • catalysts active in the electrochemical reaction of hydrogen and oxygen within the fuel cell to produce electricity may also facilitate internal reforming of hydrocarbon fuels.
  • SOFCs for example, if nickel catalyst is disposed at an electrode (e.g., anode) to sustain the electrochemical reaction, the active nickel catalyst may also reform hydrocarbon fuel into hydrogen (H 2 ) and carbon monoxide (CO).
  • both hydrogen and CO may be produced when reforming hydrocarbon feedstock.
  • fuel cells such as SOFCs, that can utilize CO as fuel (in addition to hydrogen) are generally more attractive candidates for utilizing reformed hydrocarbon and for internal and/or adjacent reforming of hydrocarbon fuel.

Abstract

L'invention porte sur une installation hybride à pile à combustible qui comprend une pile à combustible et un reformeur de carburant qui mélange un combustible hydrocarbure et de la vapeur en amont de la pile à combustible. Le reformeur convertit partiellement ou totalement le combustible hydrocarbure et la vapeur en un courant de combustible reformé qui comprend de l'hydrogène (H2), du monoxyde de carbone (CO) et du dioxyde de carbone (CO2). La pile à combustible reçoit le courant de combustible reformé à la pression atmosphérique ou à une pression supérieure et elle reçoit aussi un flux d'air à la pression atmosphérique ou à une pression supérieure, qui contient de l'oxygène (O2) et de l'azote (N2) pour produire un courant de sortie chaud de pile à combustible qui contient de l'air pauvre, du CO non oxydé et du H2 résiduel. Le courant d'air pauvre a une fraction molaire de O2 inférieure à celle de l'air d'entrée de la pile à combustible. Le courant d'échappement chaud est produit à une pression supérieure à la pression atmosphérique lorsque le combustible reformé et le courant d'air sont reçus par la pile à combustible à une pression supérieure à la pression atmosphérique. Un moteur à combustion interne ou externe produit directement ou indirectement de l'énergie en réponse au courant d'échappement chaud sous pression de la pile à combustible pour accroître le rendement de la centrale à pile à combustible. Un cycle de Rankine produit de l'énergie en réponse à la chaleur perdue extraite d'au moins un courant d'échappement chaud de la pile à combustible et du gaz d'échappement chaud produit par le moteur à combustion interne, pour accroître encore le rendement de la centrale hybride à pile à combustible pour le faire passer d'un rendement de 50 % à un rendement de plus de 70 %.
