| 摘要 |
A fuel cell stack and a manufacturing method thereof are disclosed. The fuel cell stack has at least one unit cell. The unit cell includes a first electrode collector, a first electrode layer formed on the first electrode collector, an electrolyte layer formed on the first electrode layer, a second electrode layer formed on the electrolyte layer, and a second electrode collector formed on the second electrode layer. At least one of the first and second electrode collectors may include a porous metal substrate having a density in a range from about 800 kg/m3 to about 1600 kg/m3 and a plurality of metal wires electrically connected to the porous metal substrate. The density of an electrode collector may be optimized to have an improved contact state between an electrode and the electrode collector. During operation, the fuel cell stack may thus have enhanced performance characteristics.
