All these things make most cells of the one-fluid type very unreliable, for not only is their electro-motiveforce variable, but also, as shown, their internal resistance, bothof which should be as constant as possible. These difficulties have been, to a great extent, overcome insome recent one-fluid cells, which will be described later.(See page 102, Fig. 91.) Two-fluid Batteries.—Many of the obstacles presented inthe use of one-fluid batteries are overcome by replacing the.
