“…The temperature was selected on the basis of the recent advances in SOFC that showed the possibility to work with cells at 600 C while keeping the efficiency high enough to remain in the interest of an industrial scale up [12e15] as is the case of the promising dual membrane cells [16].…”

“…Moreover, in both cases the formation of water at high temperature, associated either with hydrogen (SOFC) or oxygen (PCFC) will strongly affect the metallic interconnects durability. Later, a new SOFC design was proposed (named IDEAL-Cell) based on a dual membrane with mixed protonic and anionic conduction which combines the benefits of state of art PCFC and SOFC devices while avoiding their disadvantages due to the presence of water at the electrodes (1)(2)(3)(4)(5)(6). It is made of the anode/electrolyte part of a PCFC and of the cathode/electrolyte part of a SOFC, sandwiching a porous central membrane wherein the water is formed by the combination of H + and O 2ions.…”

“…Such systems can be studied by dielectric permittivity spectroscopy, which is a branch of the Impedance Spectroscopy applied for dielectrics permittivity properties studies. In this case the admittance Y can be presented as (10): Y(iω) = iωC = iω (C' -iC'') = ωC'' + iω C' [1] Where ωC'' can be regarded as dielectric conductivity, which involves the energy dissipative effects as ohmic conductivity, dipole's reorientation losses in electric field and others, while C' is directly related to the dielectric permittivity, i.e. to the polarization ability.…”

The present paper offers a discussion about an innovative dual membrane fuel cell concept IDEAL-Cell operating between 600 °C-700 °C. It is based on the junction of SOFCs anodic part with PCFCs cathodic part through a mixed H + and O 2conducting porous membrane. This concept was successfully proved and developed during the 4 years of a FET-Energy/FP7 project, through the collaboration between 10 European research and technological institutes. After two stages of development, respectively the proof of concept and the realization of an optimized lab-scale cell, the concept has evolved to a simplified design, called "monolithic", in which the mixed H + and O 2conduction of BCY15 is exploited for the fabrication of all the cell components. With the reduction of chemical gradients and thermal expansion mismatches, the cell durability is potentially enhanced. Furthermore, the shaping, the microstructure and the catalytic properties of the central membrane (CM) have been improved by structuring the central membrane with a Ni foam or by including Pt nano-particles. This work presents a complete study of the permeability of the central component of this concept in view of a reversible SOFC/SOEC operation, and the preliminary results obtained on this new Ni-foam based architecture by using a 3-chambers set-up (Real Life Tester) to determine the electrochemical performances of the cell in real operating conditions.

“…This cell concept was demonstrated by a set of dedicated experiments, as described in Part I of this two-part paper series. 3 Being the objective of these experiments the proof of concept of the DM-Cell, sample robustness was looked for rather than performances, and the cell design was not optimized, resulting in thick layers for different compartments and poor electrochemical performance. Much effort is currently being dedicated to the shaping of better performing cells.…”

In the dual membrane fuel cell (DM-Cell), protons formed at the anode and oxygen ions formed at the cathode migrate through their respective dense electrolytes to react and form water in a porous composite layer called dual membrane (DM). The DM-Cell concept was experimentally proven (as detailed in Part I of this paper). To describe the electrochemical processes occurring in this novel fuel cell, a mathematical model has been developed which focuses on the DM as the characteristic feature of the DM-Cell. In the model, the porous composite DM is treated as a continuum medium characterized by effective macro-homogeneous properties. To simulate the polarization behavior of the DM-Cell, the potential distribution in the DM is related to the flux of protons and oxygen ions in the conducting phases by introducing kinetic and transport equations into charge balances. Since water pressure may affect the overall formation rate, water mass balances across the DM and transport equations are also considered. The satisfactory comparison with available experimental results suggests that the model provides sound indications on the effects of key design parameters and operating conditions on cell behavior and performance.The dual membrane fuel cell (DM-Cell) is a new concept of a solid oxide fuel cell (SOFC), where the anode and the electrolyte of a protonic SOFC are connected to the cathode and the electrolyte of an anionic SOFC through a composite mixed proton-and anionconducting porous layer, called dual membrane (DM). 1 The DM-Cell, schematically represented in Figure 1, consists of five layers of porous (anode, cathode and DM) and dense (electrolytes) materials in contact. Protons formed by electrochemical oxidation of molecular hydrogen at the anode migrate through the protonic electrolyte toward the DM, where they react to produce water with oxygen anions migrating from the cathode through the anionic electrolyte.The DM-Cell presents some advantages 1-3 compared to conventional SOFC concepts, most notably referred to the fact that water is produced neither at the anode, as in anionic SOFCs, nor at the cathode, as in protonic SOFCs, rather in a third independent compartment, the DM. In the DM-Cell, water cannot come into contact with the electrodes because of the presence of the two dense electrolyte layers positioned between the DM and respectively the anode and the cathode.The scale up of the DM-Cell will necessarily depend upon the proper design of a three-chamber system (with all related issues of sealing and connections, but with some promising aspects, e.g. easy pressurization of the electrode compartments), which may prove more problematic than that of a two chamber system (as in SOFCs). In addition, the outflow of water from the DM-Cell can be critical compared to more conventional designs (protonic and anionic SOFCs), because water vapor flows in the narrow DM layer confined by two electrolytes (see Figure 1). As a consequence, any mathematical model describing the DM behavior should take into account, besides el...
