Indirectly it could help seo rank in a couple scenarios providing links are contained within the feed back to your site...

1. Some sites take your RSS feed data and repost it on their own site (XML to HTML), which if the URLS pointing to your site in the feed are left intact, will count as inbound links.

2. Additionally, if people subscribe to your feed, read the posts, visit the links to your site and add that link to their favorite social sites or own site, it could ultimately translate into more SEO juice.
