摘要： A membrane electrode assembly includes an anode including a hydrogen oxidation catalyst; a cathode; a membrane disposed between the anode and the cathode; and a peroxide decomposition catalyst positioned in at least one position selected from the group consisting of a layer between the anode and the membrane and a layer between the cathode and the membrane wherein the peroxide decomposition catalyst has selectivity when exposed to hydrogen peroxide toward reactions which form benign products from the hydrogen peroxide. The peroxide decomposition catalyst can also be positioned within the membrane. Also disclosed is a power-generating fuel cell system including such a membrane electrode assembly, and a process for operating such a fuel cell system. The assembly components contain ionomer material which can be perfluorinated or non-perfluorinated, high temperature, hydrocarbon, and the like.

摘要： An electrode element and fuel cell and a new method of manufacturing a fuel cell, particularly for use in a breath alcohol detector. This new element includes a reservoir for extra electrolyte that can allow near perfect capillary action to keep the electrode substrate full of electrolyte for long periods of time, increasing its useful life, especially under harsh conditions. Further, the capillary action need not work through a layer of electrode and can be integrally formed with the electrode element to eliminate or reduce loss due to connective surfaces. Wire connections and arrangements are generally of no concern in this design as the reservoirs for electrolyte connect directly to the substrate and electrolyte does not need to pass through an electrode.

摘要： Provided is a production method of an electrode catalyst that can reduce the content of chlorine species reliably and sufficiently through a simple operation, even when using an electrode catalyst precursor containing a high concentration of chlorine (Cl) species as a raw material of the electrode catalyst. The production method of the electrode catalyst has a core-shell structure including a core part formed on a support and a shell part formed to cover at least a part of a surface of the core part. The production method includes a first step (1) of preparing a first liquid with an electrode catalyst precursor (I) being dispersed in ultrapure water by adding the electrode catalyst precursor (I) to the ultrapure water, the electrode catalyst precursor (I) being produced using a material containing chlorine (Cl) species, and exhibiting a chlorine (Cl) species concentration not lower than a first chlorine (Cl) species concentration when measured by X-ray fluorescence (XRF) spectroscopy; and a second step (2) of preparing a second liquid by dispersing an electrode catalyst precursor (II), the electrode catalyst precursor (II) being obtained by filtrating and washing the electrode catalyst precursor (I) contained in the first liquid with ultrapure water, and then performing washing until an electric conductivity ρ of a filtrate has become a first value or lower.

摘要： The purpose of the present invention is to grasp the state in which hydrophilic groups of an electrolyte are distributed in a reaction layer for fuel cells. Nitric acid groups are bonded to hydrophilic groups (sulfonic acid groups) contained in a reaction layer for fuel cells, and metal ions capable of forming a nitrosyl complex with the nitric acid groups, e.g., ruthenium ions, are introduced into the reaction layer to dye the nitric acid groups bonded to the hydrophilic groups contained in the reaction layer. When the hydrophilic groups have agglomerated, the nitric acid groups bonded thereto also agglomerate. When said nitric acid groups are dyed with ruthenium, the ruthenium also agglomerates to make it possible to examine said nitric acid groups with an electron microscope.
