Abstract
Flat plate fuel cells, particularly air-depolarized cells, are stacked and electrically interconnected into a battery structure with a connector block and tray. The anode and cathode elements of each cell are provided with extending terminal conductor elements (e.g., banana plugs), preferably extending in downward “U” shaped configuration from the upper ends of the anode and cathode elements respectively. The connector block comprises a series of conductive apertures, positioned and sized to accommodate the terminal conductor elements of the electrodes therein and the connector block comprises electrical interconductive elements to electrically connect- the electrodes of the stacked cells in a desired electrical interconnection (serial, parallel and mixed serial and parallel segments). The interconnection between terminal conductor elements and the respective apertures further serves to support and orient the cells in a minimal volume and permits selective rapid cell removal for replacement or servicing. The cells are also provided with keyed members for keyed interlocking with a support tray having co-fitting keying elements to provide full structural integrity for the stacked cells. Lateral end elements extend between the connector block and support tray to complete an open enclosure and provide a support base for air circulating devices such as fans. Air is circulated through a duct defined by the block and between the fuel cells.
