A chemical cartridge or an oxygen generating breathing apparatus includes an outer canister and an inner canister with an interior space. At least one alkali hyperoxide or earth alkali hyperoxide that can act as an electrolyte in the presence of moisture and at least one first metallic material are provided in the interior space of the inner canister. At least one second metallic material is provided between the inner canister and the outer canister or is at least partially integrated into the outer canister wall. Between the inner canister including the first metallic material and the outer canister including the second metallic material an ion-permeable material is arranged such that the cartridge generates electrical power when in use by creating a potential between the first metallic material and the second metallic material when the at least one alkali hyperoxide or earth alkali hyperoxide is contacted by CO.sub.2 and moisture.

A system and method for modifying monoatomic oxygen levels in an initial fluid, for applications. The system and method produces both positive and negative oxygen modified fluid that retains oxygen levels for long durations as measured by oxygen reduction potential (ORP). An incoming fluid is split between a positive chamber defined by a cathode and a porous divider and a negative chamber defined by the porous divider and an anode. The relative charge over the porous divider produces fluid with elevated ORP from the positive chamber and fluid with lowered ORP from the negative chamber. A method of killing bacteria includes contacting the bacteria with negative ORP fluid produced in the system and method to the bacteria.

A chemical oxygen core for a chemical oxygen generator includes at least one layer of an oxygen-generating composition. In some examples, the at least one layer comprises includes a metal powder fuel, a transition metal oxide catalyst, and an oxygen source. In various examples, the at least one layer includes less than approximately 0.1 percent by weight of the transition metal oxide catalyst. In certain examples, a chemical oxygen generator includes a chemical oxygen core and a perforated metal covering surrounding the chemical oxygen core along a length of the chemical oxygen core. In some aspects, the perforated metal covering has an opening ratio of approximately 0 to 100 percent.
