Development and characterization of a miniature PEM fuel cell stack with carbon bipolar plates

This paper details the fabrication and testing of a fuel cell stack using a novel manufacturing approach for creating carbon bipolar plates. The fundamental fabrication techniques have been described in a previous contribution [1]. The initial paper characterized a single cell. In this work, the fabrication techniques are utilized to fabricate a three-cell fuel cell stack. Operating data in different operating conditions is measured and presented. Information on cell performance at different operating temperatures and pressures is included. The methodology for the fuel cell characterization is presented. (c) 2007 Elsevier B.V.
