Why are electrolyzers so expensive? The glass ones used in school labs are stupidly simple — just some glassware and a couple of electrodes — so why are they so expensive on an industrial scale?

Industrial electrolyzers are usually https://en.wikipedia.org/wiki/Polymer_electrolyte_membrane_e... which is a bit more complicated. But you also need to consider storing the hydrogen and turning it back into electricity.
Storing the hydrogen and transporting it to where it is needed is probably the bigger problem. Hydrogen embrittles metal.
