TEST CELL STRUCTURE ABSTRACT OF THE DISCLOSURE: A test cell structure for fuel cell or electrochemical cell technology is disclosed. Principally, the test cell may be used for testing gas diffusion or solid electrodes in a controlled environment, and such other matters as quality assurance tests of fuel cell components including electrodes, electrolytes, etc. In a simple embodiment, the test cell includes a body having an electrolyte chamber extending from one side to the other, and an electrolyte reservoir above. Reactant fluid (usually gas) chambers are formed in blocks that are secured to each side of the body, so that the gas chambers face the electrolyte chamber; and means are provided to conduct gas to and away from each of the gas chambers. Electrodes are mounted in interposed relation between the electrolyte chamber and the gas chambers at each side thereof, where the electrodes are mounted in a separable frame which, when in place, provides a fluid- tight seal between the body and each of the respective gas chambers. In a preferred embodiment, a well is formed integrally with the body as the electrolyte reservoir, having a liquid conduit communicating to the electrolyte chamber. A gas lift pump is provided for electrolyte circulation, and to provide an inert atmosphere over the electrolyte, if required. a heat exchanger may be placed into the well so as to control the operating temperature of the electrolyte.
