no. 1 Embodiment approach
[0022] figure 1 It is a plan view of the drying device 20 of the fuel cell 100 in the first embodiment. figure 2 It is a side view of the drying device 20 of the fuel cell 100 in the first embodiment. The drying device 20 includes an air blowing device 200 and a fuel cell holding device 300 (hereinafter referred to as "holding device 300"). The single fuel cell 100 is held by the holding device 300 by being placed on the holding device 300 .
[0023] Such as figure 2 As shown, the single fuel cell includes an electrolyte membrane 110 , a resin frame 120 , and two separators 130 and 140 . The electrolyte membrane 110 is made of an ion exchange resin membrane showing proton conductivity, for example, having a sulfonic acid group (-SO 3 H) A fluororesin-based ion-exchange resin membrane structure as an ion-exchange base. Catalyst layers 111 and 112 are coated on both sides of the electrolyte membrane 110 . The catalyst layers 111 and 112 each have carbon on which a cataly...
no. 2 Embodiment approach
[0036] image 3 It is a side view of the fuel cell drying device 22 in the second embodiment. Hereinafter, points different from the drying device 20 of the first embodiment will be described. The heights of the placement parts 322 , 332 , 342 , and 352 of the fuel cell drying device 22 in the holding device 302 in the second embodiment are the same as those of the placement parts 320 , 330 , and 340 in the holding device 300 of the first embodiment. , The height of 350 is different at different points. That is, the mounting parts 320 , 330 , 340 , and 350 in the holding device 300 of the first embodiment have the same height. On the other hand, in the holding device 302 of the second embodiment, the placement parts 322 and 342 have the same height, and the placement parts 332 and 352 have the same height, but the placement parts 322 and 342 are higher than the placement parts. 332, 352. Therefore, the single fuel cell 100 placed on the holding device 302 is inclined so th...
no. 3 Embodiment approach
[0041] Figure 4 It is a top view of the fuel cell drying device 20 in the third embodiment. The difference between the third embodiment and the first embodiment is the single fuel cell 101 mounted on the holding device 300 . The single fuel cell 101 includes a protrusion 137 protruding to the side opposite to the electrolyte membrane 110 to allow cooling water to flow toward the surface of the separator 130 . The separator 130 has a cooling water flow channel 138 with irregularities on the surface. The same applies to the separator 140 .
[0042] In the third embodiment, the single fuel cell 101 is placed on the holding device 300 so that the air discharged from the air blowing unit 260 and the nozzle 270 is blown toward the single fuel cell 101 along the cooling water flow path 138 . When the single fuel cell 101 is placed on the holding device 300 in this way, in addition to the effect of the first embodiment, the water 400 adhering to the single fuel cell 101 can be blo...
