Public bodies are required to provide any information requested under the Freedom of Information Act 2000, unless they can demonstrate that the information is subject to an exemption within the articles of the Act. It might be argued that travelling expenses amount to personal data which is exempt as you say, but that would be open to challenge.The assertion that the information is not a public record is an inaccurate fobbing off response, hoping you will give up. Ask the Clerk to get the council to hold an internal review the FOIR response. They must give a specific reason by reference to one or more articles of the Act why the information is exempt, or provide it. Give them 20 working days to indicate when the review meeting will be held. If they don't agree to a review, or simply say they reviewed the FOI and came to the same conclusion, submit a formal complaint to the office of the Information Commissioner.
