A fuel cell system comprises a fuel cell module, at least a cathode gas supply unit in contact with the cathode, at least one gas delivery unit and at least one anode fuel supply unit in contact with the anode. The display panel is provided to the housing body to be pivotable between a usage position where a display surface of the display panel is visible and a storage position where the display surface of the display panel is in contact with a surface of the housing body. A first end of the second rod is connected to a second end of the first rod. A generally U-shaped retaining clip is affixed to the cover and is sized to fit about and selectively engage an outwardly protruding portion of the boat. The system can include an analog-to-digital converter close to the patient parameter sensor and can transmit digital signals through a cable to the patient monitor. The reinforcing sections have a higher modulus than the composite material used to form the hollow profile.
