Abstract 1. A liquid fuel cell battery arrangement comprising: a plurality of individual circulating systems for fuel electrolyte mixture, each system including a separate fuel cell battery element, a separate associated in individual storage tank for said mixture, and means for circulating said mixture from said tank through said associated battery element and back into the same storage tank; means for introducing fuel-electrolyte mixture from outside said circulating systems into one of said individual storage tanks; means for cascading said mixture consecutively through all of said individual storage tanks, said cascading means comprising a separate overflow pipe connecting each storage tank to the next, each overflow pipe having its inlet positioned to establish a predetermined overflow level in one tank, and its outlet positioned below the predetermined overflow level in the next cascade tank; means for sensing the concentration of said mixture circulating in one of said individual circulating systems; and means responsive to said sensing means to control the flow of said mixture through said introducing means to regulate the sensed concentration.
