Process for forming integral edge seals in porous gas distribution plates utilizing a vibratory means
Patent
·
OSTI ID:5146071
This patent describes a process for producing an integral edge seal in a gas distribution plate for a fuel cell comprising providing a porous gas distribution plate; and forming a sealing layer along an edge thereof by impregnating the pores in the layer with a material adapted to provide a seal which is operative dry. When wetted by an electrolyte of the cell, the impregnating step is carried out while vibratory energy is applied to the material whereby the pores in the edge are more uniformly sealed throughout the cross-section of the edge plate.
