Scale-up of phosphoric acid fuel cells
Abstract
Development of phosphoric acid fuel cell power-plants has progressed significantly at the Energy Research Corporation. This progress has required development of both the component materials and the production techniques. Scale up of cells from laboratory size 2 in. x 2 in. cells to 80-cell 5 in. x 5 in. stacks has been successful and further scale up for stationary 100 to 1000kW powerplants is in progress. Although any optimization of scale up size depends on some basic assumptions, the present analysis is used for guiding the development effort. Considerations of reliability, simplicity, and cost indicated that a 1.25 sq ft cell with 0.75g sq ft of platinum and a DIGAS cooling system would be adequate for on-site integrated energy systems.
