    Abstract: A fuel cell module and a method of manufacturing the same. A fuel cell module including a unit cell in which a first electrode layer, an electrolyte layer, and a second electrode layer are sequentially laminated, wherein one of the first electrode layer and the second electrode layer includes a first region coated with a first electrode material layer having a first ionic conductivity, a second region coated with a second electrode material layer having a second ionic conductivity, and a third region coated with a third electrode material layer having a third ionic conductivity, and a method of manufacturing the same are provided. A temperature gradient difference of a unit cell is reduced so that more uniform performance of the unit cell may be achieved. The fuel cell module may be driven at low temperature and durability thereof may be improved.

    Abstract: A fuel cell system having no fuel pump, including: an electric generator to generate electricity by electrochemical reaction between hydrogen-containing fuel and an oxidant; and a fuel feeder including a fuel tank in which the hydrogen-containing fuel to be supplied to the electric generator is stored, wherein the fuel feeder includes a gas pressure applying unit provided between the electric generator and the fuel tank and adapted to recover gas produced in the electrochemical reaction and apply the recovered gas to the fuel tank and drive the fuel into the electric generator. With this configuration, the gas, such as carbon dioxide, produced by the electrochemical reaction between hydrogen and oxygen is supplied to the fuel tank without requiring a fuel pump, so the hydrogen-containing fuel is smoothly supplied and thereby enhances the fuel cell's efficiency in generating power.
