Abstract: An electrolytic device including a housing and at least one electrolytic cell disposed in the housing. The electrolytic cell includes a plurality of porous cathodes, a plurality of porous anodes, with each of the plurality of porous anodes disposed directly adjacent to a respective one of the plurality of cathodes so as to form a plurality of anode-cathode pairs, and a plurality of walls with each wall disposed between the porous anode and the porous cathode within each respective one of the plurality of anode-cathode pairs. At least one inlet delivers electrolyte to the porous cathodes and the porous anodes. The porous anodes and cathodes include at least partially folded portions.
