Much of the technical information about our fuel cells is proprietary. We have not yet filed for patents, but we would if we were going to license our technology for commercial production. At that time we would have to determine whether we are infringing on any Ballard patents. Our general construction is similar to Ballard's, but except for the membranes we have developed the technology ourselves. We initially developed the technology with assistance from Texas A&M. We originally used a membrane from Dupont. We are now using a membrane from W.L Gore(Gore-Tex) which has much better performance than the Dupont membrane. Based on publicly available information on Ballard, with improvements that we are making in latest version of our fuel cell, our energy density and overall performance will be comparable to theirs. A synchronous inverter(an inverter that can feed power into the electric grid) that I have for my home solar electric system is 4 kw and cost $2500. The cost per kw would have to be greatly reduced to make this cost effective for feeding the output of a fuel cell car into the electric grid. I do think that such cost reductions are feasible, but would take significant technical development and much higher production volumes.
