Ion exchange groups specified are carboxylic acid, phosphonic acid and sulphonic acid groups or salts thereof and quaternary ammonium groups such as: or in which R 1 , R 2  and R 3  may be the same or different lower alkyl group and A# is an organic or inorganic anion. Units (1) are vinyl alcohol units which may be derived by saponification of a vinyl ester copolymer.

Title: Multiple electrochemical cell system - esp for control of fuel cell battery using hydrazine/air
Inventor: JACOBS HELMUT
IPC: H01M8/04746
Filed: 1971-10-12
Abstract: Each cell has a potential sensor based on the hydrazine electrode and a reference electrode in the electrolyte close to it.
