| NETL
has completed permeability testing of the 48th composite metal membrane
foil for hydrogen separation.
This is a collaborative project with
REB Research, Los Alamos National Laboratory, Iowa State University and
Johnson-Matthey Inc. to develop membranes with high hydrogen flux and selectivity,
and improved mechanical durability.
NETL operates unique facilities for
testing the performance of membranes at temperatures (up to 1000 C) and
pressures (up to 1000 psi) not available at other laboratories. Membranes
are evaluated by testing attributes such as permeability, sealing, contaminant
exposure, multi-constituent separation and durability.
NETL also supports membrane work
being conducted by other research groups funded by NETL such as Eltron
Research Inc.
