Zusammenfassung:	PROBLEM TO BE SOLVED: To alleviate deterioration of sound deadening effect caused by water trapped in a muffler for a fuel cell. SOLUTION: The muffler is structured with an inner pipe 110 through which exhaust air passes, a muffler shell 120 covering its outer periphery, and a noise absorbing material 121 arranged between the inner pipe 110 and the muffler shell. By having the noise absorbing material made of resin, temperature fall of the muffler 100 in cold days is restrained and condensation of vapor in the exhaust air is restrained and a noise absorbing effect is improved. Further, the noise absorbing material 121 and the muffler shell 120 are both formed of a polymer material of the same quality. COPYRIGHT: (C)2004,JPO
