How can God die on a cross?
The Son of God took on a full human nature. As God he cannot cease to exist; as man he could suffer and die. The person who died on the cross is divine, but he died in his humanity — which is exactly why Scripture can speak of God purchasing the church "with his own blood" (Acts 20:28).
In more depth
The question assumes death means annihilation. In biblical terms, death is the separation of soul and body, not the end of existence — which is why the objection does not land where it seems to.
In the incarnation the eternal Son takes a complete human nature — body and rational soul — without ceasing to be divine. He is one person acting through two natures. Hunger, tiredness, suffering, and death belong to the human nature; omniscience, omnipresence, and the power to raise himself belong to the divine.
The one who died was a divine person, so Scripture can say "they crucified the Lord of glory" (1 Corinthians 2:8) and speak of "the church of God, which he obtained with his own blood" (Acts 20:28). But he died as man: his human body stopped, his human soul departed, and God did not go out of existence.
Only a man could stand in for men; only God could bear an infinite penalty and defeat death. The cross requires someone who is both.
