Abstract: A method for water mineralization is disclosed. At least one mineral that is only sparingly soluble at a pH of 7 but that is highly soluble at pH<3 is introduced into the anolyte zone of an electrolyzer, where the applied voltage creates a low-pH environment. The at least one mineral rapidly dissolves in the acidic anolyte, thereby mineralizing the anolyte. A device for performing the method is also disclosed.

Abstract: A urinary catheter is configured for avoiding heat buildup in, or even cooling, surrounding tissues when the prostate is subjected to treatment radiation such as ultrasound. The catheter includes a region transparent to ultrasound, and through which a cooling fluid (e.g., chilled water) may, in some embodiments, be recirculated during treatment. This region spans the prostate when the catheter is fully inserted (with the tip residing in the patient's bladder and a terminal balloon inflated to avoid retraction of the catheter).

Abstract: Disposable fuel cell and a system for filling a disposable fuel cell. The system includes a fuel cell having at least one chamber, a cartridge having at least one chamber, and a valve system which regulates or controls fluid flow between the cartridge and fuel cell. A method of refilling a fuel cell provides for connecting the cartridge to the fuel cell and transferring fuel and electrolyte from the cartridge to the fuel cell. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: A storage-stable liquid concentrate for use with a fuel cell. The concentrate comprises at least one metal hydride compound, a solvent comprising one or more polar solvent components, and at least one hydroxide ion providing compound. Following a storage of the concentrate for 4 weeks at about 25° C. not more than about 2 % of the at least one metal hydride compound have decomposed. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: A fuel cell for use with a hydride-based fuel, which fuel cell is designed for being sealed in a liquid-tight manner when in operation. The fuel cell comprises means for eliminating hydrogen formed inside the fuel cell. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
