Abstract
A fuel cell separator capable of improving stack performance by reducing the deviation in cell performance and diminishing dead space, and a fuel cell stack using the same are disclosed. The fuel cell separator may include a base member, a first channel group disposed on a surface of the base member and a second channel group disposed on the surface of the base member. The first channel group may include at least one channel and the second channel group may include at least one channel. The first channel group and the second channel group may extend parallel to each other in a first region of the surface and independent from each other in a second region of the surface.
Claims19
A fuel cell separator, comprising:
- a base member;
- a first channel group having at least one channel, wherein the first channel group is disposed on at least one surface of the base member;
- and
- a second channel group having at least one channel, wherein the second channel group is disposed on the at least one surface of the base member,
- wherein the at least one surface comprises a first region, a second region and a central region disposed between the first region and the second region,
- wherein the first channel group and the second channel group extend parallel to each other in the first region and the second region, and
- wherein the first channel group and the second channel group extend independently of each other in the central region.
A fuel cell stack, comprising:
- a fuel cell including an anode, a cathode and an electrolyte separating the cathode from the anode;
- and
- a separator in contact with a first surface of the fuel cell, the separator configured to supply a reactant to the anode or the cathode,
- wherein the separator comprises a base member, a first channel group having at least one channel, wherein the first channel group is disposed on at least one surface of the base member, a second channel group having at least one channel, wherein the second channel group is disposed on the at least one surface of the base member, wherein the at least one surface comprises a first region, a second region and a central region disposed between the first region and the second region, wherein the first channel group and the second channel group extend parallel to each other in the first region and the second region, and wherein the first channel group and the second channel group extend independently of each other in the central region.
