The present disclosure generally provides water electrolysis systems and methods. The systems include a first electrode set with a first bipolar plate electrically coupled to a power source. A first electrode is disposed adjacent to the first bipolar plate and in electrical contact with the first bipolar plate. The first electrode is disposed adjacent to a first side of a diaphragm. The systems include a second electrode set with a second bipolar plate and a second electrode. The second electrode is disposed adjacent to a second side of the diaphragm that is opposite the first side. A first electromagnetic conductive loop is embedded within the first electrode set. The first electromagnetic conductive loop is oriented horizontally along a vertical stand electrode plane. The Lorentz force associated with the generated electromagnetic field and the electric field of water electrolysis facilitates gas bubble expulsion from the electrolyzer system, thereby improving electrolysis efficiency.

A system for recovering of metal and sand from incinerator ash material having an ash clarification assembly, a magnet to remove the ferrous from the heavy material; a sorting assembly, a drying cage or dewatering unit to dry the material; and a separation assembly to remove the aluminum from the material. Methods are included as well.
