Removal of hydrogen and oxygen from the electrolytes of hydrogen/oxygen fuel cell batteries operating in a weightless environment.

摘要

In H2/O2 fuel cell batteries (2) which contain a freely mobile electrolyte (1) and which are operating in a weightless environment, measures have to be taken to remove the gaseous reactants dissolved in the electrolyte. For this purpose, a molar ratio of H2:O2 of 2:1 is first approximately established in the electrolyte by adding one of the gaseous reactants (8, 9) and then the hydrogen and the oxygen are catalytically (10) reacted to form water.
