Abstract
A bonding layer used to join individually formed fuel cell units together to create a solid oxide fuel cell stack can include particles contained within a carrier material. The particles can have at least one material component in common with a porous electrode of a first type and a bimodal particle size distribution. In some embodiments, the particles of a first mode of the bimodal particle size distribution are small enough to fit at least partially into the porosity of the electrodes bonded together, while the particles of the second mode of the bimodal particle size distribution are larger than the porosity of the electrodes.
