Abstract:

     A new form of hydride - fullerene-hydride - will be developed
as an innovative approach to meet new extensive requirements for
extravehicular activities (EVAs) of future, complex manned space
missions. Fullerene-hydrides, C60Hx, have a significantly improved
volumetric and weight density for hydrogen storage than the best
metal-hydrides. Preliminary thermal calculations also indicate
that this novel material could offer additional thermal
advantages. Thermal and physical properties of the C60Hx will be
determined, and the use of fullerene-hydrides in heat pump
concepts mode will be evaluated experimentally. Preliminary
engineering system design will be performed to establish the
mission suitability of the concept.

Potential Commercial Application:

Potential Commercial Applications:  Lightweight, high volumetric
density, thermally efficient hydride compounds, such as fullerene-
hydrides, are anticipated to have a wide commercial application
beyond the EVA applications, such as Ni-hydride batteries,
hydrogen purification refrigeration, and energy storage.
