Abstract
A pressure sensor adapted to provide a high resolution at a low pressure and a high pressure of an operating range is provided. The pressure sensor includes a body having an interface sur ace, a membrane sealingly disposed in the cavity adjacent the interface surface, and a sensing element in communication with the membrane. A fuel cell system including the pressure sensor is also provided.
