Solid oxide fuel cell having a dense barrier layer


A solid oxide fuel cell with a dense barrier layer formed at or near the outer surface of the top and/or bottom electrode layers in a fuel cell stack. The dense barrier layer (dbl) acts as a seal to prevent gas in the electrode layer (either air in a cathode layer or fuel gas in an anode layer) from leaking out of the stack though the outer surface of the outermost electrode layers.

Separator for fuel cell, manufacturing method thereof, and fuel cell having such a separator


A lamellar structure graphite foil is used as a material for a separator for a fuel cell, and a hydrophobic layer is formed by impregnation on flow-field channels of the graphite foil. Such a separator is manufactured by forming the flow field channel by etching the graphite foil formed with the mask pattern thereon and forming a hydrophobic layer by impregnation.

Avoiding fuel starvation of anode end fuel cell


The fuel flow channels (20a) of the end fuel cell (9a) at the anode end (34) of a fuel cell stack are significantly deeper than the fuel flow field channels (20) of the remaining fuel cells (9) in the stack, whereby fuel starvation caused by ice in the fuel flow channels is avoided during cold startup. The fuel flow field channels of the end cell (9) at the anode end of the stack is between about 0.15 mm and about 1.5 mm deeper than the fuel flow field channels in the remaining fuel cells of the stack, or between about 35% and about 65% deeper than the fuel flow field channels in the remaining fuel cells of the stack..
