"On the turn (4) 34, the work is first, and the θ must be clarified here. In the domain, the half-cell is a ": library: analysis of the fuel cell reaction. The difference between the battery is that 1 = should occur, the whole battery and half fruit, and half m' two, the relative reaction between the pole and the cathode The junction electrode, the reaction of the early electrode, this electrode is called the working electrode plate 3 / 'The invention may be an electrochemical half-cell, and the working-plate 32 may be the positive or negative electrode of the full cell. Screw r: Read: 2, Figure 3, when used, 'only need to release the detection module 4 first' will be used in the fuel cell in the gas diffusion layer, touch: cold skin into a septum 6' sub-sequential stacking Between the plates 32 of the upper plate 31, the test piece is accommodated in the working electrode plate 并 曰 323 and corresponds to the opening 3 ι of the upper plate 31, and the bolts 4i and the nuts are tightened. 42' causes the working electrode plate 32, the upper clamping plate 31 and the cover plate 36 to be pressed against the ring wall 12 of the container 1. When detecting, the working electrode plate 32 and the auxiliary are only required to be electrically connected through an electrochemical analysis instrument 7. The electrode 2' and the gas are passed into the working electrode plate 2'. The gas can be regarded as follows: The polarity of the electrode plate 32 is hydrogen or oxygen 1285739. Taking the working electrode plate 32 as an anode and passing hydrogen gas as an example, The hydrogen "decomposes into two jobs by the action of the anode catalyst, and two people see the shellfish and two electrons by the sputum, and the =:; diffuses through the _ block 34 to the chamber of the vessel 1" The two-liquid reaction [4] electrons then form a current via a circuit and then pass through the chemical analysis instrument 7 to reach the auxiliary electrode 2. Since the test electrode 5 can provide a stable reference potential, the current and potential response of the working electrode plate 32 can be measured through the test electrode 5$. Thereby, accurate analysis is performed on the modification and replacement of the test piece 6 such as the gas diffusion layer, the catalyst layer, and the quality guide film by the knife.
