Science Fair Fuel Cell Kit
Works fairly well but chemical reaction terminates prior to utilization of stored hydrogen. Connections to cell could be better - it's difficult to get the tubes on. Would benefit from an in-depth explanation of (pre-fabricated) cell construction, reaction, and catalyst.

Bought a few sheets (all from the same batch). Good uniformity of samples within the same sheet and between sheets. Good electrical conduction and good chemical purity.
