International Classification:

C25B 900

US Classification:

204252

Abstract:

The invention relates to an electrochemical cell which has an electrode, which may be either an anode or a cathode, and a membrane disposed in contact with one side of the electrode. An anode current bus is disposed on the other side of the anode, and a cathode current bus is disposed on the other side of the cathode. An anode current distributor collects current from the anode current bus and distributes it to the anode by electronic conduction, and a cathode current distributor collects current from the cathode and distributes it to the cathode bus by electronic conduction. The anode or the cathode current distributor is made of a metal which is treated by either nitriding, boriding or carbiding the metal in order to make the metal oxide growth resistant. In particular, the current distributor comprises tantalum that has been nitrided to form Ta. sub. 2 N. The current distributor thus provides a barrier between the current bus and the electrode, and the anolyte, catholyte and products of the cell.

International Classification:

F41H 5/04

US Classification:

89 3602

Abstract:

This invention pertains to a ballistic resistant article comprising at least one first layer facing a projectile and at least one second layer adjacent to the at least one first layer and facing an object to be protected wherein, under a ballistic event, the at least one first layer is capable of undergoing a shock induced non-reversible phase transformation.
