I'm trying the simulate a water splitting electrochemical reaction using the "electrochemical reaction" model in Fluent. The geometry is basically a prism, which would be the electrolyte, with an electrode on each side (for cathode and anode). It also has an inlet and outlet in the top and bottom sides. I want to have the anodic reaction (2 H2O -> O2 + 4H+) on the surface with the anode and the cathodic reaction (2 H+ -> H2) on the other surface. I've tried to follow the user's guide and what it says, but once I calculate the simulation, there doesn't appear to be any reaction. The pressure and velocity contour graphics show that there is flow of material, but there's no reaction heat nor reaction rate. I've tried the same model but with the volumetric reaction and everything works, but when I do it with the electrochemical model, there's no reaction.<\/p>\n

Maybe someone has had the same problem or knows any common mistake when doing this kind of reaction.<\/p>\n

Thanks for your help.<\/p>\n","protected":false},"template":"","class_list":["post-167700","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
