<P>PROBLEM TO BE SOLVED: To provide a porous liquid absorbing-and-holding member having strong absorptive power for a liquid owing to capillarity and having in itself a structure capable of holding a large amount of the liquid; and to provide a member for absorbing and holding an alcohol used as a fuel for a fuel cell. <P>SOLUTION: This porous liquid absorbing-and-holding member comprises a porous sintered body having a skeleton formed by sintering of metal powder around voids and subjected to hydrophilicity-imparting treatment. The hydrophilicity-imparting treatment is preferably executed by imparting one or more kinds of substances out of silicon oxides, titanium oxides, chromium oxides and aluminum oxide to the skeleton. Alternatively or additionally, the skeleton part is provided with pores having the average pore diameter not greater than 200 μm, the average void diameter is not greater than 3,000 μm, and the porosity of the whole porous body is 60-95 vol.%. This alcohol absorbing-and-holding member is used for absorbing and holding alcohol to the porous liquid absorbing-and-holding member. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
