You do not need to access your secret keys (private keys) to get your bcc.
You just need to do a different configuration of electrum in order to connect to a BCC node instead of a BTC node in order to get access to your BCC wallet.
This is no longer the case since BCC implemented two-way replay protection. BTC transactions will not be valid on BCC network... and BCC transactions will not be valid on BTC network. ThomasV is not implementing BCC support in Electrum at this time (
https://electrum.org/bcc.txt)
If you want to transact BCC, you WILL need to export your private keys into a BCC specific wallet (ref:
https://www.bitcoincash.org/ and look at "wallets"). I've seen references to an "Electrum Cash" (possibly renamed to "
Electron Cash") wallet which looks to be a fork of Electrum that is intended to work with Bitcoin Cash...
Ah, thanks HCP. I assumed they'd both work of the same software (although bip91 has been implemented to make both networks replay-proof).
It's probably a good idea to try to empty private keys before putting them into another software (especially if the developer isn't known - if ThomasV is not the producer of electrum cash).
