Demonstration model for electrolysis and cold combustion in fuel cell

摘要

A model to demonstrate electrolysis and "cold combustion" has a hermetically sealed housing (10) made of transparent material with an electrolyser 912) at the bottom, a store (14) above it, then a fuel cell (16) and on top, a header tank(18). The electrolyser comprises a block of transparent material(20) with two vertical plate electrodes (24,25), a first electrolyte chamber(26) between them, gas channels (28,29) extending upwards from the electrodes and an electrolyte channel (30) from the chamber. The store has two chambers(32,34) joined to the gas channels and a pipe (36) for the electrolyte channel. The fuel cell is also a transparent block(38) with vertical gas diffusion electrodes(44,45), a second electrolyte chamber (46) between them, two more gas channels (51,53) and another electrolyte channel (55) linking the store, plus a third upper electrolyte chamber (56)....
