Preparation.
Fuel cell electrochemical property test: the fuel cell of carbon-base film will be not coated with as blank test, by two
Kind fuel cell is placed in 0.2M H2SO4It is impregnated in solution.In dipping process, expose the area of 1cm × 1cm, rest part
It is covered with glue.After tested, carbon-base film (blank test) is not covered and covers the fuel cell of carbon-base film in different temperature
Corrosion potential and corrosion electric current density data such as table 1 under (T-300, T-400, T-500, T-600) processing.
The chemical property of 1 fuel cell of table
Experiments have shown that compared to blank control test, the functional membrane that embodiments herein provides, during the preparation process,
Carbon-base film is prepared as template as carbon source, triblock copolymer F127 by using phenolic resin, this is carbon-based thin
Film passes through different vacuum tank pressure treatment and heat treatment, tests prove that, after being coated with carbon-base film, the corrosion of fuel cell
Current potential moves 200~500mV, and corrosion electric current density reduces about 1.5 orders of magnitude relative to blank control, but temperature
After 500 DEG C, coated with carbon-base film as the fuel battery performance without coating carbon-base film, that is to say, that carbon-based thin
Film loses protective effect to the chemical property of fuel cell.
The anti-microbial property test of fuel cell: absorbance method is used, detection fuel is to mould and staphylococcus aureus
Fungistatic effect.The results are shown in Table 2.
The fungistatic effect of 2 fuel cell of table
| OD600 | |
| Blank control | 6±0.01 |
| 0.25% | 4±0.08 |
| 0.5% | 3±0.05 |
| 0.75% | 1.5±0.03 |
| 1.0% | 0±0.02 |
Experiments have shown that the fuel cell of the carbon-base film added with epsilon-polylysine has been used not generate in use
Bacterium has fungistatic effect to common mould and staphylococcus aureus, it is suppressed that the growth of bacterium makes the table of fuel cell
Face is not easy to grow bacterium, reduces the corrosion rate of fuel cell, in addition, during the experiment, it has been found that, due to making
In standby fuel cell process, while improving the frost resistance of film due to the addition of normal propyl alcohol, fuel cell has cold-resistant spy
Property, also further extend the service life of fuel cell.In addition, constituting the carbon-base film and antibacterial of the functional membrane of fuel cell
The interface of freeze proof film can isolate carbon-base film and the freeze proof film of antibacterial, make its phase into peroxide solution processing, the oxide layer
Mutual osmosis reduces, and the performance of confrontation burn into antibacterial antifreezing function plays unexpected effect.
