What makes you think significant platinum and palladium need to be consumed to produce hydrogen?
That is actually a ridiculous claim to make, given the the bulk weight of lethal lithium required for batteries.
Your phone is already more of a systemic toxic / rare Earth problem than all the solar panels and hydrogen electrolysis we could ever use.
I can tell you, as a long practicing well qualified Systems Engineer what you stated as a leading fact isn't true.
I can even tell you who has the agenda, and the funds to make such claims. You even know this already, yet still you fall for it, preferring to believe their misinformation, designed to save their business, than believe their business is the reason we are on an existential collision course with nature.
