Coplanar cell efficiency

The cell efficiency of SC-SOFCs with interdigitated electrodes was estimated to be below 1%, with a fuel utilization of less than 0.1% [63]. In addition to insufficient catalytic selectivity of the electrode materials, the small size of SC-SOFCs with coplanar electrodes limits the electrochemical conversion of fuel. 

Although the anthracene units are coplanar, there is no electronic interaction between the chromophores in the crystal. Although such an arrangement makes this class of anthracene derivatives unusable for use in applications requiring efficient charge transport (organic transistors or solar cells), the insulation of the fluorescent chromophore induced by this method may make these materials useful as emitters in OLEDs. 

Of related interest, Ramachandran and coworkers have reported a range of papers on the influence of mass transport [154-156], including diffusion-reaction problems [157]. Further work was reported on a variety of current distribution problems [158-161] in the early 1990s, with a comparison of the FEM and the BEM efficiency reported by Matlosz and coworkers [162]. A two-dimensional study of coplanar auxiliary electrodes was reported by Mehdizadeh and coworkers [163] and was used to assess the influence of the electrode configuration on uniform growth over the cathode electrode. Electroplating and corrosion protection in industrial cell configurations have also been addressed by Druesne and coworkers [164,165].
