In no way did Christ descend to hell/hades, call it what you will. Read the passage in context.
"Therefore it says,“When he ascended on high he led a host of captives,
and he gave gifts to men.”
9 (In saying, “He ascended,” what does it mean but that he had also descended into the lower regions, the earth? 10 He who descended is the one who also ascended far above all the heavens, that he might fill all things.) Eph. 4:8-10
It first talks about Christ ascending. Where did he ascend from? From the earth to heaven.
Then it talks about him descending. Where did he descend from? From heaven to the earth. This happened at the time of his incarnation.
It is talking about how Christ left his throne of glory and descended to the lower regions, which is THE EARTH. It is very clear if you read a decent translation and read it in context.
Scholars also propose that this passage could be talking about when Christ descended back to earth at Pentecost to give his gifts to the church. This makes sense, in light of the last line of verse 8 "he gave gifts to men." His descent was in the person of the Spirit.
Whichever case is right, Jesus did NOT descend to hell. On the cross when he died he said,
"Then Jesus, calling out with a loud voice, said, “Father, into your hands I commit my spirit!” And having said this he breathed his last." Luke 23:46
"It is finished!" John 19:30 Jesus died, did not go to hell/hades but went to be with the Father till the Resurrection.
