ABSTRACT:
A gaseous hydrogen and oxygen combining and condensing device comprising an inverted cup-shaped casing having a partition dividing the casing into an upper, condensing chamber a lower, catalyst chamber and a heat conducting assembly for conducting heat from the condensing chamber. The catalyst chamber being partially filled with a catalyst assembly comprising at least one catalyst support coated with a porous matrix of polytetrafluoroethylene and exposed, partially platinized high surface area carbon particles dispersed throughout the porous matrix in the weight ratio of the order of 1.5:1 to of the order of 6:1 polytetrafluoroethylene to partially platinized high surface area carbon particles. The catalyst assembly has a reduction in the loss of activity in contact with liquid water, when compared with known catalysts, so that liquid water drains over the catalyst assembly as a coolant without loss of activity of the catalyst and reducing the risk of hot spots occuring in the catalyst which can cause an explosion.
