The present invention provides a novel means for generating hydrogen gas which is particularly useful in domestic applications, particularly, a hydrogen-fueled gas fireplace. The hydrogen generating means comprises a filter-press electrolyzer that generates hydrogen from an electrolyte solution and has a relatively small size, e.g., about 600 mm2, and is thus convenient for domestic use. Suitable domestic applications include cooking stoves and the like as well as gas fireplaces. A hydrogen-fueled fireplace comprises a housing containing a firebox, an electrolyzer, which comprises a series of electrolytic cells, and a power module.

1. A self-contained power module comprising an enclosure having input and output connectors for providing an electrical interface between an exterior and interior of the enclosure, said module comprising:a first full-wave rectifier having an input connected to the input connector of the enclosure, and an output, a chopper having an input connected to the first full-wave rectifier output, and a chopped output having a variable duty cycle, a transformer having a primary winding coupled to the chopped output, and a secondary winding; a second full-wave rectifier having an input coupled to the secondary winding ofthe transformer, and an output connected to the output connector of the enclosure such that a rectified sinusoidal waveform appears at the output connector when an AC voltage is applied to the input connector; and a controller for regulating the duty cycle of the chopped output as a function of the AC voltage.
