Electrically conductive deformable coating for high temp. fuel cell electrode

Coating an essentially planar, plate-shaped component (partic. a bipolar plate and/or an electrode) of a high temp. fuel cell, with an electrically conductive, easily deformable layer is done by fine spraying. A ceramic and/or metal contact material powder (10, 12) with a particle size distribution...

Beschreibung
Zusammenfassung:	Coating an essentially planar, plate-shaped component (partic. a bipolar plate and/or an electrode) of a high temp. fuel cell, with an electrically conductive, easily deformable layer is done by fine spraying. A ceramic and/or metal contact material powder (10, 12) with a particle size distribution from 0.1-50 mu m is mixed with a bonding system (18). The bonding system contains at least one organic and/or inorganic bonding agent (14) and at least one solvent (16).
