The studies about hydrogen fuel which consist of hydrogen extraction and reforming process, fuel cell equipment, and receptacle are flourishing all over the world. But, Korean hydrogen station is still underdeveloping. And also a hydrogen compressor which is the most important part at the hydrogen station, has not been developed. Snubber is one of the most important parts in hydrogen compressing system. Snubber has function to reduce pulsation waveform and to remove the impurities in the hydrogen gas. A snubber has an inclined plate as a buffer, which is installed inside snubber. When the pressure loss and the pulsation of pressure within a snubber is minimized, the snubber could get more applicability. Therefore, a study to find an optimum geometric size on a several snubbers which have different buffer width, has been conducted using a numerical analysis. The numerical results show the special characters of snubber according to various buffer angle. The minimum pressure loss ratio occurs when the buffer angle is 35. and the minimum pressure pulsation ratio occurs when the buffer angle 10.
