A water-containing solid fuel drying apparatus that can efficiently dry with low energy consumption by effectively utilizing sensible heat and latent heat of a heating medium for drying, etc. is provided. A drying apparatus () that dries water-containing solid fuel includes a dryer () that injects scavenging gas into the interior of a drying vessel () in which a heat transfer pipe () is disposed; a dust collector () that removes microparticles from microparticle-containing mixed gaseous fluid that has flowed out of the drying vessel (); a compressor () that compresses vapor-containing mixed gaseous fluid; a vapor heat exchanger () that preheats low-pressure mixed gaseous fluid with high-pressure mixed gaseous fluid compressed at the compressor (); and a gas-liquid separator (), in which the high-pressure mixed gaseous fluid is employed as drying gas that radiates heat by passing through the heat transfer pipe (), that performs gas-liquid separation of water-containing scavenging gas that has flowed out of the heat transfer pipe () while containing condensed water of vapor generated due to heat radiation, wherein the water-containing solid fuel is dried by heating the water-containing solid fuel in the drying vessel () utilizing latent heat and sensible heat of the mixed gaseous fluid.

Water-containing solid fuel drying apparatus and drying method

The present invention discloses a base tube for a fuel cell produced by forming a film of a fuel electrode and a film of an air electrode on a surface of the base tube, the base tube comprising a mixture of a raw material for the base tube, and coarse particles, whereby the mixture shrinks nonuniformly when sintered to increase the porosity of the base tube. Thus, the gas permeability and the cell electrical efficiency can be increased.
