Using nanoporous, nonprecious metals to produce hydrogen via metal hydrolysis for fuel on-demand in nonstationary applications is a promising method to overcome infrastructural deficiencies associated with current hydrogen storage and delivery systems. However, these highly reactive nanoporous nonprecious metals are also highly pyrophoric, which prompts safety concerns if the fuel is improperly exposed to air. Herein we demonstrate a new strategy to suppress pyrophoricity in nanoporous metals such as nanoporous aluminum created by electrolytic dealloying by forming composite pellets with highly hygroscopic materials such as lithium borohydride. [1-2] We show that composite pellets with various compositions are highly air stable and are not pyrophoric when exposed to ambient air. These safety improvements can pave the way to using nanoporous nonprecious metals for on-demand hydrogen generation fuels for nonstationary fuel cell devices and applications.  T.
