Designs of SOFC Stacks

Many designs have been proposed for SOFC stacks as listed in Fig. 4.9, but two of them have been running successfully, viz. tubular and planar design. 

Each design may have variants, but the seal-less tubular designs, microtubular designs, and bipolar flat-plate (planar) designs have received wide attention. Hence, the discussion in the present section is limited to tubular (seal-less), microtubular, and planar designs only. The design of SOFC usually depends on three criteria as follows.
