Lavrentieva, 15, Novosibirsk, Russia4 International Science and Technology Center, Moscow, RussiaFuel cells are electrochemical reactors which directly convert chemically storedenergy into electrical energy at high thermodynamic efficiencies.Most fuel cell power plants (FCPP) use methane as a fuel which is reformed in acatalytic fuel conditioning system and converted into a gas enriched with hydrogen tobe used in a fuel cell stack (FCS) for the electrochemical oxidation reaction.Methane steam reforming is the most well studied, efficient and most widely usedmethod of hydrogen production in the fuel cell based power plants.In most FCPPs, catalytic steam reforming is performed in separate fuelprocessors. The fuel processor is a chemical reactor which requires heat supply tofunction. As a heat source, natural gas with addition of the FCS products is generallyused, i.e. gas mixtures containing a certain amount of combustible components, suchas H 2 , CO and CH 4 . In [1] various schemes of integrated fuel processors for fuel cellapplication are reviewed. The most efficient schemes are those of internal reforming,which is attractive from the perspective of increased system compactness andefficiency, faster loading response and significant cost reduction. Direct addition of areforming catalyst into the anode material is proposed for solid oxide fuel cells(SOFC) [2], and an integration of a reforming catalyst separated from the hot anodeby a heat conducting wall is proposed for SOFC and molten carbonate fuel cells [3].One of the most most important elements of the FCS which distributes the fueland the oxidizer flows in the FC anode and cathode zones and provides electriccoupling of cells is a separator (in planar SOFC – interconnector). Theseparator/interconnector is a plate profiled from a flat metal sheet, where channelsfor distribution of gas flows are formed (Fig. 1.).The goal of this work is development of an integrated separator/interconnector fordirect reforming of hydrocarbons in high-temperature MCFC and planar SOFC.
