What is the essential advantage of a fuel cell
over other types of galvanic cells that are
used to generate electrical energy?

The main advantage of a fuel cell over a battery is that a fuel cell can provide continuous electricity due to the ability of, uh, providing a continuous amount of reactant as the reactant is consumed, more reactant can be added where in a battery, the reacted is contained in a compartment, and once it's used up, it's used up, and the battery needs to be thrown away or recharged.

In this question. We want to know the purples off salt rage. We don't know that in a note. The unknown If it's metal, we know it lost electron, so it increased the number off time. So here, increase combines. Why in castled in castle gain electron. So it help any compliant Toby the Baltic and left czar line. So za mali remaining increase. Now if we live these eyes as it we found that electrical double layer is forming and the no further electron transfer here. So the rule off that salted bridge is that so the bridge is containing electrolyte, which it contained a pines also under online, which is that a mine is new from castle toe stop lines disease, excess combine or is a time for me And here the time is D views near the remaining online dry to making balance. So without sort of rage, we found that the number off electron transfer here is nearly view. But with the presence off the soldier page, we found there are electoral transfer here which more postive, maybe for me and more on mine may remain. Thank you

So in this video, we're going to be talking about Question 32 from Chapter 20 which asks, what is the function of assault bridge in a voltaic cell? So let's go ahead and use an example to talk about this. We're gonna talk about the example reaction of zinc plus C B plus two forming zinc plus two and copper. Um, so we have our oxidation half reaction and which zinc is oxidized. Zinc plus two and our reduction half reaction in which copper plus two is reduced to a solid copper eso what's happening and honorable to excel. So we have our oxidation happening at Theano. So we have a zinc strip at her anode, connected by a conducting wire of some kind to our cathode, which is a copper strip. Um so as the reaction proceeds were forming these ink plus two ions at our anode. So we have this buildup of positive charge around her anode. And then in our cathode we hade these positives See you plus two I owns and solution. And now they're now they're being deposited a solid copper. Um so So we're have a buildup of negative charge around our cathode and build up a positive charge around her and know that's going to keep these reactions from proceeding longer than just immediately after connecting the wire eso. In order to allow this reaction to proceed further, we have to connect these two solutions. Um, with what we call assault bridge. So we form assault bridge where we have a solution of, um, positive and negative ions that can flow freely between your solution around your anode and your solution around your cathode. So you don't have positive charge building up around your anode and negative charge around your cathode. Usually these ions take the form of like potassium ions for a positive ions and chloride ions for our negative ions, just some kind of counter ions to balance the charge. And the salt bridge allows those ions to flow freely between solutions to keep the buildup of charge to keep these solutions neutral and allow our reaction to proceed on dhe, then are electrons will continue to flow from our anode to our cathode because we have the salt bridge allowing that to happen

And Richmond is necessary in order to have an operational fuel rod. Enrichment is the process of increasing the concentration of uranium to 35 which is the fissionable material from its natural amount 0.7% Teoh a more reasonable amount of three point of 3 to 4%. This is typically done by Floren ating the uranium atoms to 35 to 38 then separating them using Graham's law of diffusion.
