Functionalized Graphitic Supports for Improved Fuel Cell Catalyst Stability

Physical Sciences Inc. (PSI) together with the University of Connecticut (UCONN) proposes to demonstrate the improved fuel cell catalyst support durability offered by directly incorporating nitrogen functionality into graphitic carbon supports. In Phase I, PSI will utilize the functionalized carbon support in the construction of single cell fuel cells in order to demonstrate the performance and durability of the support material in the PEM fuel cell environment. The performance of cells upon accelerated life testing will be characterized and compared with that of cells assembled using commercially available support materials to quantify the benefits offered by the functionalized support. In Phase II, PSI will work with UCONN to optimize and scale-up the support production processes. Incorporation of additional functionalities will also be investigated. Demonstration cells will be constructed and delivered for functional and environmental testing at the completion of the Phase II contract.
