I wonder how much more efficient. This process would have benefits where high density energy is needed, hydrogen powered container ships being a popular plan of mine. But if you don’t have space constraints, involving a hydrogen fuel cell only adds inefficiencies. Most fuel cells are in the 64-80% efficiency range, which the theoretical max being 84%. This might be worse off than the PV->battery->use pipeline that we’re used to.
