Where can I buy a Genuine new battery to install on my iPhone X ?

There is Self Service Repair - Apple Support

but I don't think they sell parts for your model phone.

Take the phone to an Apple Store or authorized Apple Service shop. That is the only way to get a genuine Apple battery. About $89 U.S.

Find Locations

Apple does not sell genuine batteries to any shops that are not authorized.

Find an authorized shop in the link that was provided. But, they won't sell you the battery unless they install it.

Thx for reply. What about the ones that are offered on eBay by Genuine resellers?

There is no such thing. The seller is lying.
