Materials in catalytic converters recycled to make fuel cells that boost mileage 5 times over regular internal combustion engines?

Could CeO2 for these fuel cells be recycled from catalytic converters? The platinum recovery might pay for the process.

The high melting point of the material could be attained with a solar furnace.

Surface contaminants and the remaining platinum could be vaporized from the surface with concentrated solar power, then the CeO2 melted and purified and formed into the appropriate shape.

Technology that feeds off of recycled internal combustion vehicles to produce new fuel cell electric vehicles could be very cost effective.

Rather than a whole new vehicle, remove the ICE parts then install the fuel cell electric parts recycled from parts from other applications, like three phase industrial motors, turbo chargers, and catalytic converters.

It looks like first adopters of these new systems will be do it yourselfers not large industrial automakers.
