<P>PROBLEM TO BE SOLVED: To provide a liquid fuel retainer for fuel cell arranged in a fuel cell using methanol as a liquid fuel and a manufacturing method thereof, capable of giving birth to the fuel cell excellent in absorptivity of the liquid fuel and capable of maintaining high electromotive power for a long time. <P>SOLUTION: The liquid fuel retainer for a fuel cell is made by heat treating soft polyurethane foam manufactured by using foaming materials containing polyol, isocyanate, catalyst, a foaming agent, a foam stabilizer, and a silane coupling agent. The foam stabilizer contains a polyorganosiloxane-polyether block copolymer having a structure in which its polyether parts are combined through Si atoms of the polyorganosiloxane parts and one or more CH<SB>2</SB>groups, with a density of the liquid fuel retainer for the fuel cell of 60 to 130 kg/m<SP>3</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT |
