Through alignment and grading of pores one can tailor surface areas and diffusion channels for flows of gas and liquid species involved in fuel cell reactions.
Porous ceramics tape casting.
Tape casting is a well established technique to fabricate ceramic tapes.
Several techniques have been used to fabricate porous ceramics such as slip casting 14 organic foam impregnation 15 extrusion 16 tape casting 1 and direct foaming 17.
Tape casting of porous materials tape casting is a standard shaping technique used to produce flat ceramic sheets with a thickness range varying between 10 μm to 1 mm.
This technique has been usually applied to produce dense substrates for electronic applications but recently there are.
