A method of optimizing a waveform of an electrical current applied to an electrode of an electrochemical device that consists of at least two electrodes separaged by an electrolyte that includes the steps of: applying an electrical current to an electrode of a device; determining a waveform of the voltage or the current of the electrical current; representing the waveform by a mathematical expression or numbers taking measurements of output voltage, current or power of the device associated with the application of the electrical current; and varying the shape and frequency of the waveform to optimize the output voltage, current or power of the device and thereby determine an optimized waveform of the electrical current to be applied to the electrode of the device.

Methods of removing contaminants from a fuel cell electrode

A method of optimizing a waveform of an electrical current applied to an electrode of an elecetrochemical device that includes at least two electrodes separated by an electrolyte, includes the steps of: applying an electrical current to an electrode of a device; determining a waveform of the voltage or the current of the electrical current; representing the waveform by a mathematical expressions or numbers; taking measurements of output voltage, current or power of the device associated with the application of the electrical current; and varying the shape and frequency of the wave form to optimize the output voltage, current or power of the device and thereby determine an optimized waveform of the electrical current to be applied to the electrode of the device.

A method of inhibiting corrosion in ammonia-water absorption machines that includes adding to an ammonia-water solution soluble silicon compounds. Examples of these silicon compounds include sodium silicate (Na.sub.2 SiO.sub.3), potassium silicate (K.sub.2 SiO.sub.3), lithium silicate (Li.sub.2 SiO.sub.3), silicic acid (H.sub.2 SiO.sub.5), and tetramethoxysilane (CH.sub.3 O).sub.4 Si. Sodium silicate is revealed as the preferred embodiment.
