Most of UPS-Systems use batteries as back-up energy source. Usually here we find lead-acid batteries or NiCd batteries when high ambient temperature. If longer back-up times are required an additional diesel generator will provide the energy. This paper presents the results of some tests, where a fuel cell system generates the back-up energy on a 48V level.
