power density on the earlier cell was approx. 1/2 watt/sq. cm. cell membrane. Cell size tested was about 4" square (1 layer): therefore approximate cell are = 103sq cm x .5 watt=51.5 watts x2 (factor for percentage power increase = 103 watts/layer x1.15 (factor for retesting of advanced cell = 118 watts. Now assume each layer of the cell is 3/8" thick then we say a cell with 10 layers makes 1.18kw of electricity. If the assumption for cell thickness is correct and our extrpolation of past results is close then a 50kw cell (equal to Ballards latest would be 50kw/1.18kw=42.3 so say 43 layer thick x 3/8" = a cell size of 4"x4"x16" long. This does not include the cell casing etc. It is also a rough figure extrapolated from currently available information. GLE apparently will be putting a FAQ section on their site however which will more accurately answer your question. Additionally I have requested power generation capability in watts and the voltage. Watts is meaning less to SOME extent if one does not know what voltage something produces. Hope this helps for now.
