A hydrogen blower is provided and includes a housing having a drive unit and a compressor unit disposed therein. The drive unit is separated from the compressor unit by a neutral chamber, whereby the neutral chamber effectively seals the drive unit from the compressor unit. The drive unit includes a drive shaft, whereby the drive shaft extends generally between the drive unit and the compressor unit to selectively drive the compressor. In addition, the drive shaft fixedly supports a series of fan blades such that rotation of the drive shaft imparts a pressure on the neutral chamber to effectively seal the drive unit from the compressor unit. In this manner, the drive motor, compressor, and drive shaft may be packaged in a single housing while effectively sealing the drive unit from the compressor unit through cooperation between the fan blades and the neutral chamber.
