The invention provides a water-activated, deferred-action battery having a housing containing at least one cell, comprising at least one anode selected from the group consisting of magnesium, aluminum, zinc and alloys thereof; a cathode comprising a skeletal frame including conductive metal and having a portion of its surface area formed as open spaces, and further comprising a heat-pressed, rigid static bed of active cathode material encompassing the skeletal frame, the cathode material being formed of cuprous chloride, sulfur, carbon and a water-ionizable salt and being compacted and fused under pressure and heat to itself and to the skeletal frame, to form a heat-fused, conductive, electrochemically active phase; at least one cavity separating the cathode and the at least one anode, and at least one aperture leading to the at least one cavity for the ingress of an electrolyte-forming, aqueous liquid.

Water-activated battery

The invention provides a single pass wet fabrication process for preparing a gas diffusion electrode for metal-air batteries and fuel cells comprising:

Process for preparing a single pass gas diffusion electrode

The invention provides a gas diffusion electrode containing a fiber reinforced composite structure in a layer thereof, the structure comprising structurally intact fibers precoated with sinterable polymeric material, which material is heat sintered, whereby the fibers are bonded to each other and to other components of the structure by the sintered polymeric material, while maintaining their individual fibrous structure and strength.
