[0096] [Structure of Electrochemical Hydrogen Compression Device]
[0097] Figure 2A with Figure 2B It is a figure which shows an example of the electrochemical type hydrogen compressor of embodiment. Figure 2B A plan view of the anode gas diffusion plate 31 of the electrochemical hydrogen compression device 100 is shown.
[0098] Figure 2A with 2B In the illustrated example, the electrochemical hydrogen compression device 100 includes a cell 40 , a voltage applicator 21 , a dew point regulator 22 , and a controller 50 . Here, the unit cell 40 of the electrochemical hydrogen compression device 100 includes an electrolyte membrane 1 , an anode AN, a cathode CA, a cathode separator 5C, and an anode separator 5A.
[0099] The electrolyte membrane 1 is provided with a pair of main surfaces and has protons (H + ) conductive membrane. The electrolyte membrane 1 may have various structures as long as it is a membrane having proton conductivity. For example, examples of th...
no. 1 Embodiment
[0169] The electrochemical hydrogen compressing device 100 of the present embodiment is the same as the electrochemical hydrogen compressing device 100 of the embodiment except for the following control contents of the controller 50 .
[0170] The controller 50 controls the voltage applicator 21 to compress a part of the hydrogen in the hydrogen-containing gas supplied to the anode AN without compressing the rest of the hydrogen.
[0171] Here, assuming that the total amount of hydrogen in the hydrogen-containing gas supplied to the anode AN is compressed from the anode AN of the unit cell 40 to the cathode CA, excess condensed water stays in the anode AN, and thus the anode AN may Overflow occurs. Then, the diffusion overvoltage of the cells 40 of the electrochemical hydrogen compressing device 100 may increase.
[0172]Therefore, the electrochemical hydrogen compression device 100 of the present embodiment is controlled as described above, and by recirculating a part of the...
no. 2 Embodiment
[0183] The electrochemical hydrogen compressing device 100 of this embodiment is the same as the electrochemical hydrogen compressing device 100 of the embodiment except that the hydrogen-containing gas supplied to the anode AN includes the hydrogen-containing gas generated by electrolysis of water.
[0184] That is, in this case, image 3 Hydrogen from a hydrogen source is generated in a water electrolysis device (not shown). Furthermore, for example, a water electrolysis device can generate hydrogen using electricity generated from renewable energy sources such as sunlight. In addition, the water electrolysis method of the water electrolysis device may be any method. Examples of water electrolysis by the water electrolysis device include solid polymer water electrolysis and the like.
[0185] Here, the hydrogen-containing gas produced by electrolysis of water contains water vapor. For example, the hydrogen-containing gas is in a high-humidity state with a dew point of abo...
