Description
Technical field
The utility model relates to fuel cell field, is specially a kind of electrolytic cell for measuring oxygen reduction reaction.
Background technology
Fuel cell is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) chemical energy in fuel and oxygenant being converted into electric energy by the electrocatalytic reaction on electrode.It is by the restriction of Carnot cycle, can be electric energy by chemical energy efficiently.Proton Exchange Membrane Fuel Cells (PEMFC) has quick startup, easily discharges without electrolyte loss, water, the life-span is long, specific power and the outstanding feature such as specific energy is high, is suitable as portable with power supply that is electric automobile.See: people's document 1 (" Experimental Methods for Quantifying theActivity of Platinum Electrocatalysts for the Oxygen Reduction Reaction " Anal.Chem.2010 such as Yannick Garsany, 82,6321 – 6328)
Proton Exchange Membrane Fuel Cells in the application topmost challenge is that the dynamics of cathodic oxygen reduction is comparatively slow, needs more and outstanding eelctro-catalyst.The performance characterization of oxygen reduction electro-catalyst be unable to do without convenient and practical hydrogen reduction electrolytic cell.
The shortcoming that the electrolytic cell that PINE company provides exists is: electrolytic cell volume electrolytic solution that is large, that need is more; Electrolytic cell cleaning is inconvenient, needs to clean electrolytic cell, blocking, O-circle etc. simultaneously; Electrolytic cell ventilatory effect is bad; Fixing electrode and contrast electrode position of electrolytic cell not easily changes.Novel electrolytic tank of the present invention, overcomes above-mentioned shortcoming well, more convenient and flexible in design, and makes simple, cheap.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems, provides a kind of electrolytic cell for measuring oxygen reduction reaction, and this electrolyser construction is simple, easy to clean, and volume is little, saves solution; Adopt core intake method, up to a hundred minute bubbles fine uniform ground produce simultaneously, be conducive to the saturated rapidly of solution, and minute bubbles can not blow to electrode surface; To electrode and contrast electrode, can select arbitrarily and place arbitrarily, more flexibly.
The technical solution of the utility model:
For measuring an electrolytic cell for oxygen reduction reaction, by electrolytic cell spheroid, form electrode tube, reference electrode tube, draft tube, bronchus and leg, electrolytic cell spheroid is uncovered spherical vessel, and electrolytic cell bottom is provided with draft tube; The side of electrolytic cell spheroid be positioned to electrode tube and communicate with bottom electrolytic cell spheroid, to being provided with glass core in electrode tube, the electrode tube mouth of pipe being ground and filling in mill fixing to electrode; Reference electrode tube communicates from opposite side with electrolytic cell spheroid, and one end of reference electrode tube is positioned at the center of electrolytic cell spheroid and is provided with Luggin capillary mouth, and the other end mouth of pipe of reference electrode tube is ground and is fixed by ground and salt bridge; Glass core is provided with in the pipe of draft tube; Liquid feeding or protection gas branch pipe are arranged at side, electrolytic cell spheroid top; Electrolytic solution is installed in electrolytic cell spheroid and in electrode tube; Electrolytic cell is by leg stands alone.
The utility model has the advantages that: this electrolyser construction is simple, and volume is little, save solution, adopt core intake method, up to a hundred minute bubbles fine uniform ground produce simultaneously, be conducive to the saturated rapidly of solution, and minute bubbles can not blow to working electrode surface; To electrode and contrast electrode, can select arbitrarily and place arbitrarily, more flexibly.This electrochemical cell not only may be used for measuring oxygen reduction reaction, also may be used for the experimental study that other need to pass into the reaction atmospheres such as nitrogen, argon gas, hydrogen, carbon monoxide, carbon dioxide.
