摘要:
A fuel cell electrode which can improve the catalyst utilization rate by having the catalyst component supported at a high density and high dispersion is provided. An aqueous solution containing chloroplatinic acid and aniline is prepared. For an electrode diffusion layer, a carbon paper is soaked in a Teflon® dispersion solution and then dried. One side of the electrode diffusion layer is placed in contact with the liquid surface of the solution, and a counter-electrode made of graphite is provided in the solution. A constant electrical current is applied between them, with the electrode diffusion layer side as the positive electrode. As a result, aniline is oxidatively polymerized by electrochemical means, and a uniform layer of platinum-containing polyaniline is formed on the electrode diffusion layer surface. The platinum in the polyaniline is reduced, and this is washed with pure water and dried to make the electrode. Two of these electrodes, with the catalytic layer of the platinum-containing polyaniline on the inside, are placed against both sides of Nafion® to create a small fuel cell.
摘要:
This invention provides a catalyst for a fuel cell electrode, a process for producing a catalyst for a fuel cell electrode, a membrane electrode assembly, and a fuel cell, which are advantageous in suppressing aggregation of a carbon support such as carbon nanotubes, and in closely contacting the three of the carbon support, a catalyst component and an electrolyte component with each other. A catalyst for a fuel cell electrode contains a carbon support (e.g., CNTs) having a pi-conjugated system, an electrolyte component having an aromatic ring, and a catalyst component. A process for producing a catalyst for a fuel cell electrode. By contacting, in a solvent, a carbon support (e.g., CNTs) having a pi-conjugated system, an electrolyte component having an aromatic ring, and a catalyst component with each other, the carbon support can be modified with the electrolyte component and loaded with the catalyst component.
摘要:
An electrolyte for electrochromic elements which comprises an electrolytic base material to conduct ions and charge-controlling substances contained in the electrolytic base material. The electrolytic base material is composed of a polar organic solvent and a supporting electrolyte and the charge-controlling substance is at least one of oxidizable substances and reducible substances. This electrolyte enables to produce durable electrochromic elements which can balance the charges in both electrodes and avoid a residual color or an uneven color of coloring materials.
