Hydrogen storage system and fuel cell stack represent the two most important components in H2-powered fuel cell vehicles. At present, each technology faces its own challenges. For example, for practical applications, the on-board hydrogen storage system must meet the targets set by U.S. DOE on gravimetric/volumetric densities and the cost ($2/kWh) by 2015. These requirements pose significant challenges to a storage material development. For hydrogen to electric energy conversion, the proton exchange membrane fuel cell is the device of the choice. Major technology barriers include the electrode catalyst cost and durability in PEMFC stack.  In this presentation, we will discuss our recent progresses in developing nano-porous organic polymers as new H2 adsorbents and aligned carbon nanotubes as novel electrode support for PEMFC. The preparation of these nanomaterials and their impact to the system performance will be provided. Furthermore, their structure-property relationships will be discussed from various characterization studies.
