Submarine oxygen-generating

Later, Du Pont in America developed its own ionically conducting membrane, mainly for large-scale electrolysis of sodium chloride to manufacture chlorine, Nafion , (the US Navy also used it on board submarines to generate oxygen by electrolysis of water), while Dow Chemical, also in America, developed its own even more efficient version in the 1980s, while another version will be described below in connection with fuel cells. Meanwhile, Fenton et al. (1973) discovered the first of a... 

Membrane electrolysis technology is well established and appropriate for smaller scale facilities. One application is its use as an oxygen generator in submarines, where the hydrogen is considered only a byproduct. Drawback is the high-cost membrane production [14].

The cell design is similar to that of fuel cells . SPE electrolysers are commercially available for small scale, oxygen generators used in space craft and submarines and also for large scale hydrogen production using off-peak electricity. 

Self-contained rescue devices, a type of chemical oxygen generator, are used in mines (usually coal mines) to provide oxygen to miners after a fire or an explosion. However, they can be dangerous when stored because of their explosive capabilities and have been implicated in some mine disasters. They have also been targeted as a source of explosions on submarines. 

The carbon dioxide generated by the personnel in the artificial atmosphere of submarines and spacecraft must be removed from the air and the oxygen recovered. Submarine design teams have investigated the use of potassium superoxide, K02, as an air purifier because this compound reacts with carbon dioxide and releases oxygen (Fig. 4.16) ...

Promise of law or zero emissions - Fuel cells operating on hydrogen generate zero emissions - the only exhaust is unused air/oxygen and water. This may be attractive not only for transportation but also for many indoor applications, as well as submarines. However, hydrogen is not a readily...
