Problems solved by technology

However, this can be difficult to achieve without creating undue pressure drops along the fuel and oxidant flow paths due to the reduction in the flow path caused by compression of the fuel cell stack, which compression can increase the load on the fuel cell stack. Happening

Abstract

An electrochemical cell stack having a plurality of electrochemical cells stacked along a longitudinal axis. The electrochemical cells include a membrane electrode assembly having an anode plate and acathode plate with the membrane electrode assembly interposed therebetween. The electrochemical cells also include an anode plate and a cathode plate with the membrane electrode assembly interposed therebetween, and the anode plate defines a plurality of channels that form an anode flow field facing the anode catalyst layer. The electrochemical cells further include a cathode flow field positioned between the cathode plate and the cathode catalyst layer, wherein the cathode flow field comprises a porous structure.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 62 / 618,221, filed January 17, 2018, which is incorporated by reference in its entirety. technical field [0002] The present disclosure relates to electrochemical cells, and more particularly, to electrochemical cells with improved fluid flow design. Background technique [0003] An electrochemical cell, generally classified as a fuel cell or an electrolysis cell, is a device used to generate an electrical current from a chemical reaction or to induce a chemical reaction using the flow of electrical current. For example, a fuel cell converts the chemical energy of a fuel (eg, hydrogen, natural gas, methanol, gasoline, etc.) and an oxidant (air or oxygen) into electricity and waste products of heat and water. A basic fuel cell consists of a negatively charged anode, a positively charged cathode, and an ion-conducting material called an electrolyte. [0004] Different fuel cell technologies utilize...
