Techniques and systems involve a magnetically enhanced cryogenic boiler that produces, without requiring pumps, high pressure gaseous oxygen from liquid oxygen for use in a spacecraft or other applications. The boiler heats, using a heat exchanger element, a closed container of liquid oxygen to boil the liquid oxygen at constant volume and increasing the pressure in the container. When a desired target pressure is reached, the boiler may release and transfer the high pressure fluid into a gaseous oxygen accumulator for storage. Magnets may be used to draw low pressure liquid oxygen into the boiler and to keep the liquid oxygen on or near one or more heat exchanger elements in the boiler, by exploiting paramagnetism of oxygen. The magnets produce a magnetic field that maintains relatively strong thermal contact between the heat exchanger elements and the liquid oxygen, even in the absence of gravity.
