  • Publication number: 20180274112
    Abstract: Disclosed is a membrane electrode assembly that includes a polymer electrolyte membrane, a first electrochemical reaction layer formed on one side of the polymer electrolyte membrane to allow an oxidation reaction to occur thereon, a first electron-conductive layer formed between the polymer electrolyte membrane and the first electrochemical reaction layer, a second electrochemical reaction layer formed on a remaining side of the polymer electrolyte membrane to allow a reduction reaction to occur thereon, and a second electron-conductive layer formed between the polymer electrolyte membrane and the second electrochemical reaction layer. The first electron-conductive layer and the second electron-conductive layer include a porous metal.

  • Patent number: 9944544
    Abstract: Disclosed is a 3-dimensional porous mono-polar electrode body that includes a 3-dimensional porous parent substance, which has a 3-dimensional structure including a side and a remaining side that communicate with each other via a plurality of pores arranged in multiple layers and which is made of a metal material to have dimensional stability, and an electrode catalyst layer applied on the 3-dimensional porous parent substance. The 3-dimensional porous mono-polar electrode body is used to remove microorganisms contained in treatment water to thus minimize the consumption of power, which is required to remove the microorganisms, prevent secondary pollution, and ensure the durability of an electrode.

  • Publication number: 20180051380
    Abstract: Disclosed is a reinforced composite membrane for water electrolysis, and a membrane electrode assembly having the same. More particularly, the present invention relates to a reinforced composite membrane for water electrolysis, and a membrane electrode assembly (MEA), wherein a two-dimensionally woven fabric base, layer that, minimizes swelling of the membrane in the X-axis and Y-axis directions is covered on a hydrogen electrode to which high pressure is applied or on hydrogen and oxygen electrodes by three-dimensionally electrospun reinforcing fiber layers, the reinforcing fiber layers minimizing swelling of the membrane in the Z-axis direction, thereby reducing permeation of oxygen (O2) via the hydrogen electrode and enabling operation under high pressure due to high dimensional stability.

  • Patent number: 5808278
    Abstract: An appliance capable of being operated in compliance with the Orthodox Jew requirement that no work shall be done on the Sabbath. The applicance has a control system that monitors and controls all of the components of the applicance. The control system can be activated so that it prevents all visual displays and audible alarms from being actuated by the user during the Sabbath. The control system also prevents any actions of the user from causing the machine to do work.
