Abstract

A system is disclosed for removing electrolyte from a fuel cell gas stream. The gas stream containing electrolyte vapor is supercooled utilizing conventional heat exchangers and the thus supercooled gas stream is passed over high surface area passive condensers. The condensed electrolyte is then drained from the condenser and the remainder of the gas stream passed on. The system is particularly useful for electrolytes such as phosphoric acid and molten carbonate, but can be used for other electrolyte cells and simple vapor separation as well. 3 figs.

Glycol reboiler vapor condenser

Patent McGrew, R.; Broussard, J.P.

A method is described for controlling the emission of aromatic compounds from a glycol reboiler, including steam and vaporized hydrocarbons, during glycol dehydration, comprising the steps of: (a) heating used glycol and water in said glycol reboiler to a temperature in the range of 350 to 400 degrees Fahrenheit; (b) directing steam and vaporized hydrocarbons from said glycol reboiler to a centrally disposed cylinder in a vapor condenser by a first conduit; (c) providing said vapor condenser with a cooling water spray through a second conduit connected to a source of liquid water and said centrally disposed cylinder for sprayingmore »« less
Process for removing electrolyte vapor from fuel cell exhaust gas

Patent Sederquist, R. A.

Electrolyte vapor entrained in the hot exhaust gas stream from a fuel cell is removed by passing the gas stream through a saturator, over high surface area material, in direct contact with water circulating in a loop which also passes through the saturator. The hot gas stream evaporates a small portion of the water, resulting in cooling of the gas stream and condensing of electrolyte therein as it cools. The electrolyte dissolves into the recirculating water. The water is exchanged at predetermined intervals or when the concentration of electrolyte reaches a predetermined level. At least 99% of the electrolyte canmore »« less
Low-maintenance lead--acid batteries having electrolyte reservoir in vapor contact with the cells

Patent Biddick, R.E.

These batteries have a porous, nonconducting membrane which separates the reservoir from the cells but allows replacement by vapor diffusion of water lost by electrolysis and evaporation. Oxygen can also be transferred from positive to negative plates. (RWR)
B _xC _yN _z nanotube formation via the pressurized vapor/condenser method

Patent Jordan, Kevin; Whitney, R. Roy; Smith, Michael W.; ...

Nanotube filaments comprising carbon, boron and nitrogen of the general formula B _xC _yN _z, having high-aspect ratio and high-crystallinity produced by a pressurized vapor/condenser method and a process of production. The process comprises thermally exciting a boron-containing target in a chamber containing a carbon source and nitrogen at a pressure which is elevated above atmospheric pressure.
