Hydrogen Generator

This exciting new product is, we believe, the best way of providing hydrogen to the many small fuel cells, e.g. those made by H-TEC, that are avaliable today. Compared to other methods (such as electrolysers, metal hydride systems, and high pressure cylinders) it is safer, simpler and lower cost.

The basis of operation is as follows. A very small amount of Sodium Borohydride is added to some water. A special platinum catalysed reactor is then added to the solution, which promotes this chemical reaction:-

NaBH₄ + 2H₂O à NaBO₂ + 4H₂

The gas is formed as a steady, long lasting stream of bubbles, as shown in the picture below.

The outlet pipe can be connected to small fuel cells. About 0.1g of sodium borohydride will last for an hour or more, depending on the current drawn. In the picture below the HGEN is fuelling an HTEC cell, which is powering a small radio via one of our AU01 DC/DC converters.The outlet pipe can be connected to small fuel cells.
