 PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY (electrochemical processes or apparatus in general C 25; semiconductor or other solid state devices for converting light or heat into electrical energy H 01 L, e.g. H 01 L 31/00, H 01 L 35/00, H 01 L 37/00) [2]
 

Notes

(1)

 This subclass covers galvanic primary or secondary cells or batteries, fuel cells or batteries.

(2)

(i)

 liberate, separate or purify a pre-existing compound or composition, or to
 

(ii)

 treat textiles or clean solid surfaces of materials
