Definitions
- the present specification relates to a planar solid oxide fuel cell. Specifically, the present disclosure relates to a plate-type solid oxide fuel cell sequentially provided with an anode, an electrolyte layer, and an cathode.
- a fuel cell is a power generation system that converts chemical reaction energy of a fuel and an oxidant into electrical energy.
- Hydrogen, a hydrocarbon such as methanol, butane, and the like are typically used as an oxidant.
- Fuel cells include polymer electrolyte fuel cells (PEMFC), direct methanol fuel cells (DMFC), phosphoric acid fuel cells (PAFC), alkaline fuel cells (AFC), molten carbonate fuel cells (MCFC), and solid oxide fuels. Batteries (SOFC) and the like.
- PEMFC polymer electrolyte fuel cells
- DMFC direct methanol fuel cells
- PAFC phosphoric acid fuel cells
- AFC alkaline fuel cells
- MCFC molten carbonate fuel cells
- SOFC solid oxide fuels.
- FIG. 1 schematically illustrates the electricity generation principle of a solid oxide fuel cell
- the solid oxide fuel cell includes an electrolyte layer, an anode, and a cathode formed on both surfaces of the electrolyte layer. do.
- oxygen ions are generated as the air is electrochemically reduced in the cathode, and the generated oxygen ions are transferred to the anode through the electrolyte layer.
- fuels such as hydrogen, methanol, butane, and the like are injected, and the fuel is combined with oxygen ions to oxidize electrochemically to produce electrons and produce water. This reaction causes the movement of electrons in the external circuit.
- the present specification is to provide a planar solid oxide fuel cell. Specifically, the present specification is to provide a planar solid oxide fuel cell sequentially provided with an anode, an electrolyte layer, and an cathode.

Full sintering simultaneously at 1500 ° C. for three hours.
- the manufactured unit cells were photographed from the air electrode side (left) and the fuel electrode side (right) and are shown in FIG. 5.
- the anode extends in a direction opposite to the direction in which the cathode is provided based on the ceramic support, and extends in a direction opposite to the direction in which the cathode is provided based on the ceramic support as a current collector of the anode.

- the prepared unit cell was photographed from the air electrode side and illustrated in FIG. 4.
- Open circuit voltage (OCV) was measured according to the temperatures of the examples and the comparative examples, and the results are shown in FIG. 6.
- OCV refers to the voltage difference in a state where no current flows (the state in which no work is performed). The higher the OCV value, the better the cell performance. The most important factors affecting the OCV value are electrolyte stability and gas sealing. In other words, if the electrolyte is sufficiently stable, the OCV value is high, and if the reaction gases (fuel and air) are completely sealed and all of the electrochemical reactions occur without a combustion reaction, the OCV value is close to the theoretical value. The low OCV of the comparative example seems to be due to a gas leak near the electrolyte / fuel electrode / fuel electrode current collector since the gas sealing portion was not all covered with the electrolyte. In other words, it is difficult to completely seal the gas with the existing current collector method, which results in low OCV.
- Example or Comparative Example After raising the unit cell manufactured in Example or Comparative Example to a target temperature (850 ° C.), the current is gradually increased while supplying hydrogen to the anode and air to the cathode. Collect potential change data continuously and calculate the output at each temperature. For more detailed electrochemical analysis, alternating current impedance experiments are performed in parallel, and the electrochemical reaction at the corresponding frequency is inferred from the Nyquist plot of the impedance obtained from the high frequency and the low frequency as the input signal. .
- FIG. 7 is an I-V-P curve generally showing the performance of a fuel cell.
- the gas seal was incomplete, resulting in a low OCV value, which resulted in a low performance of about 1/2.
- the current collection of the anode is carried out in the fuel supply direction as in the embodiment, since the entire surface can be coated with the electrolyte, gas sealing is easy and high OCV values can be expected.
