Claim 1:
2. The broadband resonator for a fuel cell compressor according to claim 1, wherein
the entrained water removal system further includes:
at least one axially elongated rotational positioning rib formed on the at least one radially inner enclosing surface of the resonator housing extending along the lower portion of the resonator chambers;
wherein the notch openings formed in the annular disk-shaped walls receive and engage the at least one axially extending rotational positioning rib, the notch openings extending radially inwardly from the outer circumference of the annular disk-shaped walls, the notch openings engaging the at least one axially extending rotational positioning rib to lock a rotational position of the tubular pipe within the resonator insert receiving chamber;
wherein entrained water drains from a lower portion of the resonator chambers through the notch openings and along the at least one axially extending rotational positioning rim, further forming the drainage channel draining water towards the outlet opening at the second axial end to the entrained water re-entry hole.
