Claim:
A galvanic electrochemical cell ( 100 , 300 , 700 , 900 ) for converting chemical energy into electrical energy comprising: a. an outer cylinder-like current collector ( 106 , 304 X , 306 X , 710 X , 902 X ) surrounding an inner cylinder-like current collector ( 108 , 314 X , 316 X , 712 X , 906 ) so as to define a gap ( 118 , 324 , 724 , 924 ) between the current collectors ( 106 , 304 X , 306 X , 710 X , 902 X ; 108 , 314 X , 316 X , 712 X , 906 ), one of the current collectors containing at least two electrically conducting azimuthal segments ( 106 X , 304 X , 306 X , 702 X , 902 X ) that are electrically isolated from each other by an azimuthal insulator segment ( 106 C , 400, 708 X , 908 X ) and the other of the current collectors containing at least one electrically conducting azimuthal segment ( 108 , 314 X , 316 X , 710 X , 906 )—the electrically conducting azimuthal segments being adapted for connection to an external electrical circuit ( 114 ); b. means ( 128 , 130 , 136 , 142 , BOP) for circulating fluid in the gap ( 118 , 324 , 724 , 924 ); c. a cylinder-like filter ( 120 X , 326 , 726 , 910 ) located in the gap ( 118 , 324 , 724 , 924 ) having 1. an azimuthal ion-porous particle filter segment ( 120 P , 326 P , 726 P , 910 P ) and 2. an azimuthal non-porous segment ( 120 N , 326 N , 726 N , 910 N ); and and dividing the gap ( 118 , 324 , 724 , 924 ) between the outer and inner collectors ( 106 , 304 X , 306 X , 710 X , 902 X ; 108 , 314 X , 316 X , 712 X , 906 ) into outer and inner electrolyte chambers; and d. means ( 126 , 128 , 130 , 526 , 528 , 530 , 626 , 628 , 630 ) for providing relative rotation between the filter ( 120 , 414 , 520 , 620 ) and one of the current collectors ( 106 , 506 , 606 , 108 , 508 , 608 ) to create flows ( 144 , 146 , 148 , 150 , 336 , 338 , 728 ) in fluid located in the gap ( 118 , 324 , 724 , 924 ).
