I voted not top 100. Even if this works (I'm somewhat skeptical short of more proof), the product is not economic at either their current manufacturing cost ($18,522 for 300 Wp or $61.74 per Wp) or their target rate ($5,000 for 300 Wp or $16.67 per Wp). The use of water for fuel is just a curiosity because the cost is greater than that of traditional fuel cells AND their fuel costs.

I would also want to know about their stack life. Stack life is a huge problem for all fuel cells - many of which have lives measured in hours (typically 6 months to 4 years of continuous operation. For this product to achieve grid parity, it would need a 20 year stack life at 9.5 cents per KWH grid prices or 10 years at 19 cents per KWH.
