The present invention is a back-up power supply of alternating current and direct current, with the alternating current being generated by an inverter from the direct current, which is produced by a fuel cell. The inverter is at least partially encompassed by a phase changing material having an elevated melting point such that the phase changing material absorbs heat generated by the inverter as well as in the surrounding air, thereby maintaining the inverter temperature within acceptable limits. As the phase changing material absorbs the heat, its tempe...


What is claimed is: 1. A power system for meeting alternating current (AC) and direct current (DC) demands at a telecommunications site, comprising: a source of alternating current (AC), said source connected to an AC demand and to a DC demand via a rectifier; a back-up source of direct current (DC) connected directly to said DC demand; and an inverter connected to said back-up source of DC for converting at least a portion of DC to AC for supply to said AC demand, and wherein said inverter is at least partially encompassed by a phase changing material ...
