The air compressor includes an on position in which the air compressor is configured to supply air to the fuel cell stack and an off position in which the air compressor does not supply air to the fuel cell stack. The air compressor also includes a bearing configured to be levitated via air. The air pump is configured to supply air to the fuel cell stack when the air compressor is in the off position and configured to supply air to the bearing when the air compressor is in the on position.
