I don't think there is commercial products but there is research.

To do so you have to use a Solid Oxide Electrolyse Cell operating above 600 °C.

Thanks Dr. Paul Gateau

I am looking for electrolyzer that can work between ~100 °C to ~ 200 °C but as you mentioned SOE cell works above 600 °C.

The problem is steam : if you have pressurized water above 100°C you could use water electrolysers.

Thanks, Dr. Paul Gateau for the explanation.
