Abstract: <P>PROBLEM TO BE SOLVED: To prevent transpiration of liquid fuel and to hold the loss of the liquid fuel to a minimum in a fuel tank feeding fuel by its self-contraction power.  <P>SOLUTION: In the fuel tank, an inner container storing liquid fuel is provided in an outer container. The inner container has a double structure consisting of a partition wall made of a fluorocarbon resin and an elastic member surrounding the outside the partition wall. Since the partition wall directly contacting with methanol is formed of a fluorocarbon resin, the liquid fuel such as methanol does not permeate therethrough, and thus the transpiration of the liquid fuel is prevented. Furthermore, since the outside of the partition wall is surrounded by the elastic member, elasticity is given to the inner container, and the liquid fuel stored in the partition wall is pushed out by the contraction power of the elastic member. Thus, the fuel can be fed smoothly.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
