Abstract
Abstract A battery of interconnected high-temperature rechargeable electrochemical cells, a method of operating the battery and support means for supporting and heating the battery are provided. The support means acts to carry the cells and to heat the cells from below. Heating the cells from below is electrical and/or by circulating heated gas through a plinth on which the cells rest, the gases being derived from the catalytic conversion of a hydrocarbon fuel.
