摘要： The invention includes an electrolytic cell for gas-developing or gas-consuming electrolytic reactions and processes, and an electrolysis process therefor. According to the invention, the capillary slit electrode has conduits enabling the separate flow of reaction gas and electrolyte/permeate in the electrode. The electrode is preferably hydrophilic in a narrow internal region for mounting on a separator, while elsewhere it is hydrophobic. Thus electrolyte/permeate penetrates only into the region of the capillary slit electrode near the separator, while the region away from the separator remains free of electrolyte/permeate, so facilitating the unimpeded flow of the reaction gas. The invention is applicable especially in electrolytic cells for chlor-alkali or hydrogen electrolysis, and in the construction of cells for the generation of power.

摘要： An electrolysis cell for gas-emitting or gas dissipating electrolytic processes using at least one electrode having a capillary structure in its edge region (51, 52) on the reaction side such that the gas (6) and electrolyte (L) are substantially conveyed there transversely to the electrode and in which there is a capillary slit adjoining this edge region which offers substantially less resistance to the conveyance of the gas and electrolyte along the vertical electrode plane than the edge region. The preferred embodiment are a plurality of foil-like (44), mutually supported, shaped electrode components. The process of the invention for running the electrolysis cell makes full use of its ejector effect, i.e. it supplies itself with electrolyte when the level of electrolyte in the cell is greatly reduced.

摘要： A porous electrode for a fuel cell is made by dusting nickel powder of a particle size of 65 to 75 microns into a dish-shaped plate and sintering without pressure at a temperature between 1325 DEG C. and 1350 DEG C. for an hour in hydrogen or a mixture of hydrogen and nitrogen. A second layer having finer pores is then produced on the first layer by painting on it a suspension in alcohol of nickel powder having a particle size of 4 to 5 microns and sintering at 1000 DEG C. for half an hour. In an alternative method of making the first layer, nickel particles of size 7 to 9 microns or 4 to 5 microns are mixed with ammonium bicarbonate of 100-240 mesh in the proportion of 1 part by weight of the bicarbonate to 3 to 5 parts of nickel. The mixture is pressed at 4,000 lbs. per square inch and then sintered at 1000 DEG C. to 1150 DEG C. for half an hour to 3 hours. The Provisional Specification describes modifications of the sintering processes in one of which the temperature at which the coarser nickel particles of 65 to 75 microns are sintered is reduced to 1150 DEG C. by sintering in an atmosphere of hydrogen and nitrogen which has been passed through hydrochloric acid.

摘要： An innovative fuel cell system with membrane electrode assemblies (MEAs) includes a polymer electrolyte membrane, a gas diffusion layer (GDL) made of porous metal foam, and a catalyst layer. A fuel cell has a metal foam layer that improves efficiency and lifetime of the conventional gas diffusion layer, which consists of both gas diffusion barrier (GDB) and microporous layer (MPL). This metal foam GDL enables consistent maintenance of the suitable structure and even distribution of pores during the operation. Due to the combination of mechanical and physical properties of metallic foam, the fuel cell is not deformed by external physical strain. Among many other processing methods of open-cell metal foams, ice-templating provides a cheap, easy processing route suitable for mass production. Furthermore, it provides well-aligned and long channel pores, which improve gas and water flow during the operation of the fuel cell.
