XCHAOS: mohl bys svoje tvrzeni nejak podlozit? protoze je to opak toho, co ctu...
co se tyka platiny, to je o technologii

co se tyka objemu, ja nechci v patek v noci delat chemickou resersi, ale kdyz mas sportaka na 1600km ve vodiku, kterej jezdi 355km
https://evcentral.com.au/hyperion-xp-1-355km-h-1600km-hydrogen-hypercar-revealed/
a o chlup vetsi teslu na baterky s dojezdem 500km a omezovacem rychlosti, protoze by se baterie vyjela za 100km na plnej plyn, tak to neco vypovida o hustote energie a jejim skladovani.
je potreba si uvedomit, ze jsme sice vodik pouzivali uz pred 100 lety, ale tehda nebyl internet (vic hlav vzdycky vic vi), startup incubatory, klimaticka krize, levna ropa a tak obrovskej objem investic do alternativ. u vodiku jsme teprve na zacatku cesty...
taky se nesmis fixovat jen na elektrolyzu, ale treba vodik misto skladkovani:

...a i elektrolyza pujde dopredu

The CHANNEL (Development of the most Cost-efficient Hydrogen production unit based on AnioN exchange membrane ELectrolysis) project will run until December 2022. It aims to develop a low-cost and efficient electrolyser unit utilising “non-PGM electrocatalysts, porous transport layers, current collectors, bi-polar plates, state-of-the-art anion exchange membranes and ionomers,” as noted on the project website. “This will enable the development of an electrolyser technology at a capital cost (CAPEX) equal or below classical alkaline electrolysis. However, in contrast to the alkaline technology, the CHANNEL AEM electrolyser will have an efficiency and current density operation close to the one of proton exchange membrane electrolyser (PEMWE).” The project website also states: “The CHANNEL stack will not only result in decreased electrolyser part count, but it will also be able to operate at differential pressure, as well as under dynamic operation, optimal for producing high quality, low cost hydrogen from renewable energy sources.”
