The present invention provides an apparatus and method to generate optimally sized microbubbles and/or nanobubbles of hydrogen gas, oxygen gas and/or oxyhydrogen gas according electrolysis cell parameters and voltage and/or size and/or volume of water in a water reservoir or from a flow of water. In a water reservoir a control unit is operable to control water pump means to pump water at a predetermined velocity through the electrolysis cell according to the parameters of the electrolysis cell to control the average size of the nanobubbles and/or microbubbles generated, and the water flow at the predetermined velocity shears the generated nanobubbles and/or microbubbles from the electrodes into the water flow and through the water outlet of the apparatus. In a water flow, a control unit operable to adjust voltage to the electrolysis cell, whereby the amount of the voltage adjustment is made according to the rate of flow of water and to the parameters of the electrolysis cell to control the average size of the nanobubbles and/or microbubbles generated, and wherein the flow of water shears the generated nanobubbles and/or microbubbles from the electrodes into the water flow and through a water outlet.

An electrochemical cell that generates hydrogen has an anode including an electrochemically oxidizable substance and an electrode designed for hydrogen generation as a cathode and an aqueous alkaline electrolyte. The anode and the cathode are designed such that the hydrogen generation begins at the cathode as soon the anode and the cathode are electrically connected to one another. At least one resistance foil is adhesively bonded to at least one outer side of the housing which, when it is connected as a load resistance between the anode and the cathode, reduces the current flow between the anode and the cathode and therefore also the gas generation rate.
