Yes, you'll need to get a BCC compatible wallet... and then after the fork happens, you'll need to export your seed (or private keys) from Electrum and then import your seed (or private keys) into that BCC Wallet.
Electrum IS NOT compatible with BCC... You cannot create/send or receive BCC transactions with Electrum.
