Fuel Reservoir for Fuel Cell

A fuel reservoir for a fuel cell detachably connected with a fuel cell main body, wherein:

• the fuel reservoir is equipped with a fuel-storing vessel for storing a liquid fuel and a fuel discharge part;
• the fuel discharge part is equipped with a valve for sealing communication between the inside and the outside of the fuel-storing vessel;
• the inside of the fuel-storing vessel is communicated with the fuel cell main body by inserting a liquid fuel-supplying member into the valve, thereby forming a communication part that communicates the inside of the fuel-storing vessel with the fuel cell main body and through which the liquid fuel in the inside of the fuel-storing vessel is supplied to the fuel cell main body;
• the valve comprises an elastic material and has an elliptic form or a circular form in a cross section;
• the communication part is a slit which is provided in a minor axis direction of the ellipse or a diameter direction of the circle;
• and
• a major axis of the ellipse or a diameter of the circle in the direction rectangular to the slit is compressed to a shorter length than a length thereof.
