I don't know if there are any other members on the board that are still here from a long time ago who can verify what I said. Most are gone. When SolCool dropped Neah, SolCool dropped Neah's EL series fuel cell from their website. The link is no longer there for that product. From what I remember the cost was $5000 for a 50 watt unit. I also remember they didn't disclose or have any information about cartidges to recharge the fuel cell. That's all I can remember. I haven't checked but I think SolCool still has a website and a product line of what they sell. It was well over a year ago that I ever went to their site.
