Abstract

See full text

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 CO2 and moisture.
