What are the best methods to quantify urea before and after urea electrooxidation experiments in terms of cost, speed, and accuracy?

I am using a nickel anode in an electrochemical cell to oxidize urea in very alkaline solutions (pH 13.5). I want to quantify urea before and after the experiment. Many different methods have been...

Is there a different name for an electrochemical cell with electrodes separated by a liquid electrolyte than one with a membrane electrode assembly?

An example of the former would be a cell with two electrodes made on FTO glass and the latter might be electrodes synthesized on carbon paper or cloth and pressed on either side of a proton...

How does current travel from the anode in a fuel cell MEA to the current collector and then to the cathode if the two elements are not in contact?

I am looking to construct my first photocatalytic fuel cell. I want to construct a membrane electrode assembly for it to reduce the inter electrode distance and thus decrease the proton diffusion...

What is the best, inexpensive (i.e., <$300) alternative to a Hg/HgO reference electrode when working with very alkaline solutions (e.g., NaOH > 1M)?

I want to find a relatively low-cost Hg/HgO reference electrode for 3-electrode linear sweep polarization curves, cyclic voltammetry, and chronoamperometry. I am having trouble finding many...
