Abstract
A fuel cell module includes a cell unit including an electrolyte membrane, a cathode disposed on one face of the electrolyte membrane, and an anode disposed on the other face of the electrolyte membrane, and a water reservoir which stores water produced at the cathode. The water reservoir includes an opening formed in a region other than the cathode of the cell unit, and a projection projecting from the opening to an anode side. The water covering a cathode surface of a fuel cell is reduced.
Claims10
A fuel cell module, comprising:
- a cell unit including an electrolyte membrane, a cathode disposed on one face of the electrolyte membrane, and an anode disposed on another face of the electrolyte membrane;
- a fuel chamber provided on the other face of the electrolyte membrane to contain the anode, the fuel chamber being configured to collect a fuel to be supplied to the anode;
- a water reservoir provided adjacent to the cell unit, the water reservoir being a part of the fuel chamber to enclose a space in which the fuel is collected, wherein
- said water reservoir comprises a protruding part protruding into the space of the fuel chamber,
- the protruding part has an internal space for storing water from the cathode, and
- the protruding part is formed of the electrolyte membrane.
