Answer:
No, the plates are made of solid titanium and galvanized with platinum in several layers, baked and sprayed to achieve the densest possible surface. The manufacturers usually state the durability of these panels as 30 years, but in my opinion that depends on how they are used. I don't know of a 30 year old ionizer because I've only been using it for 16 years. I have already seen plates with partial loss of the platinum titanium surface on a device that was 15 years old. This is not critical because titanium is also used as a joint replacement in the body. But the electrolysis performance then decreases because the platinum surface area required as a catalyst is no longer as large. Another case is ECA devices like those from Kangen or our Aquavolta Water Tractor, where salt is added to the water, which has an aggressive effect on the anodes. That's why we strictly separated the drinking water cell (without salt) from the functional water cell (with salt) in our device. With long devices, on the other hand, everything runs through the same cell, and on such cells you can see worn surfaces after just 5 years.
Where does the platinum disappear to over the years?
It dissolves in water as so-called platinum nanoparticles, which have been discussed as a cancer therapeutic agent since the 90s. The Japanese researcher Prof. Sanetaka Shirahata writes: “Ionized alkaline water contains a high concentration of dissolved hydrogen (0,4-0,9 ppm) and a small amount of platinum nanoparticles (Pt nps, 0,1–2,5 ppb), both of which are Have the ability to neutralize free oxygen radicals.” Here is all the work from 2014: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4212634/

The latest study is from 2019 https://pubs.acs.org/doi/10.1021/acsnano.9b05124 But the entire research direction is ahead an issue especially in Japan, while the mainstream in the USA, China and also my thoughts focus more on the effect of molecular hydrogen.
