Abstract
Project of the invention is the carbon and the electrode ink that constitutes of water or water and alcohol system that catalyst is coated with by electrolyte solution, supported to dielectric film that is thin and also deforming in air, is made without the membrane electrode assembly of deformation.Solution is to assign enhancing band to the both ends of the electrode ink coated face of the dielectric film with backboard, form first electrode, even if removing the backboard of dielectric film in order to form opposite electrode, also enhancing band is attached in two end sides of dielectric film, so between heating adsorption roller, there are aeration substrates, strength attraction is carried out, so even if dielectric film is also indeformable in order to form second electrode and coating electrode is black.Apply binder in two end sides of aeration substrate further, it is possible to substitute enhancing band, the uncoated portion of two end sides of dielectric film is bonded, so higher effect can be obtained.
Description
Technical field
The present invention relates to PEFC (Polymer Electrolyte membrane Fuel Cell, polymer dielectric film
Fuel cell) type fuel cell electrode forming method and the fuel cell that is produced using this method.
More specifically, be related to CCM (Catalyst coated membrane, catalyst coat film) formula dielectric film and
Electrode forming method.Coating in the present invention is not particularly limited, including roller coating, die coating, silk-screen printing, curtain painting, ingredient, spray
Ink, apply the atomization (include fibrosis) comprising spraying, apply electrostatic atomization (including fibrosis) etc. be coated with particle, fiber
In the method for coated article, also comprising applying micro- curtain.
Whens micro- curtain is with the relatively low pressure of 0.3MPa or so spraying liquids such as the aeration jet of wide-angle shape etc.,
The method for being coated with coated article and nozzle traversing using the liquid film part before becoming mist, did not generated spraying grain in coating surface
Son.Become misty if passing through coated article and leaving distance.
Refer in addition, applying atomization (fibrosis), using spraying other than progress particlized, uses with ultrasonic wave, electrostatic
The rotation of spinning etc., the centrifugal force of rotary body, melt-blown mode etc. are come the method that makes particle, fiber, as needed by compression
The method that the power (air assist, gas auxiliary) of gas makes liquid, molten mass etc. adhere to or be coated on object.
Background technique
In the past, it mixes by a kind of electrolyte solution as ionomer and is supported in carbon particle, carbon on dielectric film
The micro mist of the compositions such as the platinum on fiber is coated on GDL (Gas diffusion layer, gas diffusion as electrode catalyst ink
Layer) and it is attached to dielectric film, and/or be coated on the mold release films such as PTFE and be needed on dielectric film.The pressure subsidiary formula method and turn
Liquid is not present in India side formula, therefore resistance is generated between dielectric film and electrode, declines the performance of fuel cell.In order to solve
The problem proposes the method that the electrode catalyst ink of CCM mode is directly coated at dielectric film.
Patent document 1 is the method invented by the present inventor, is proposed by the electricity of roll-to-roll (Roll to Roll)
Solution plasma membrane uncoiling is simultaneously adsorbed in the state of warmed-up absorption drum and/or absorption band, and electrode ink is laminated using spraying etc. and applies
The method that cloth makes it dry.Spraying etc. is used in the state that dielectric film is adsorbed and heated by the heating of absorption drum etc.
It is laminated with film, so spraying particle instantaneously volatilizees in the moment solvent for being coated on dielectric film levelling.It therefore will not be to electrolysis
Matter causes damage and adaptation improves, so the limit can be reduced to the interface resistance of electrode and dielectric film, so can
Form ideal CCM.In addition, proposing between absorption drum and electrolyte, there are the paper of the width aeration wider than dielectric film
And/or film attracts dielectric film, so making the absorption trace of the porous body of absorption drum etc. uniform attraction electrolyte not remainingly
Film surface is whole.
Patent document 2 is also the method invented by the present inventor, proposes the electricity at roll-to-roll (Roll to Roll)
Film of the two sides fitting of plasma membrane as the mask of electrode shape is solved, the recess portion of electrode shape is formed, by its uncoiling with warmed-up
With absorption and the method being coated with to be wound is laminated in electrode ink by adsorption roller and/or absorption.In addition, also proposed to covering
The method that the recess portion catalyst filling micro mist of the electrode shape formd between mould and dielectric film forms electrode.It pushes away in the method
Attraction and coating electrode are carried out to dielectric film via aeration substrate warmed-up absorption drum etc. when recommending coating electrode ink
Ink.
CCM mode is ideal, but dielectric film is to sensitivities such as moistures, in short time set when coating electrode catalyst ink,
Therefore, it attempts that dielectric film is made to be adsorbed in heating absorption band and/or heating adsorption roller etc. to not deform as previously described
With the coating such as nozzle and/or slot nozzle in the state that ground is mobile.But even at room temperature with grinding device by roundness
A few micrometers of adsorption rollers below are ground to, since its structure is complicated, big deflection deformation can also occur for roller when heated, just
Circularity becomes very poor.Therefore, if carried out using the method for being referred to as slit and/or slot nozzle contacted across liquid film,
The distance change of nozzle tip and dielectric film generates distance and leaves excessive position.In case of such phenomenon, electrode ink
Coating weight it is few, therefore, because becoming cavernous for more than quantity of solvent and electrode ink that viscosity is low is with the relationship of film coated
It is extremely difficult to obtain even spread for coated face.In order to solve the project, in the Japanese Unexamined Patent Publication 2010- invented by the present inventor
In 149257, proposes grinding Suction roll surfaces in the state of being heated to using temperature and roundness can be made to become 5 microns
The following method.In addition, proposing will adsorb in the Japanese Unexamined Patent Publication 2015-15258 for being estimated as grinding adsorption roller at normal temperature
The roller of dielectric film is cooled down, and electrode ink is coated on dielectric film with gap nozzle, will be made roller moving in rotation and is adsorbed in
The method that electrode ink hot wind and/or infrared ray on the dielectric film of chill roll are heated.But catalyst in this method
Drying after coating weight be such as 0.1 milligram every square centimeter, be 0.3 milligram in cathode in anode, be thin film, thus i.e.
Make the roundness of roller being set as 3 microns, also requirement must impact dielectric film for not wet at a distance from nozzle tip
Film thickens.Therefore, can envision must be set as such as 15% or less for the solid component that electrolyte solution and catalyst add up.
Then, it is conceivable that, until between dry section, even if in the presence of for inhibiting electricity caused by solvent (mixed solvent of water and alcohol system)
The absorption for solving wet and deformation the powerful vacuum pump of plasma membrane, also damage caused by solvent can occurs at the interface of dielectric film.
