Abstract: An electrolysis cell is controlled for operation under varying electrical power supply conditions. A flow of feed stock to the cell includes an electrolysis reactant at a controlled concentration. A varying amount of electrical power is supplied to the cell to produce an electrolysis reaction that generates a first reaction product at a first side of the cell and a second reaction product at a second side of the cell. The reactant concentration is adjusted as the electrical power varies to substantially maintain the cell at its thermal neutral voltage during cell operation. The cell may be used in an electrolysis system powered by a renewable energy source with varying power output (e.g., wind, solar, etc.).
