Of course the number of incoming/outgoing links is the most important factor for google pagerank but its not the only one. Your website number of pages does have an affect on your pagerank and this is how I see it:
Short term:
You add 100 new pages to your website now, your pagerank will drop in the next update. Thats because the old pages will leak/give pagerank to the newest pages.
Long Term:
Your pagerank dropped last update due to the leak, but this time it will increase because you already have 100 pages that are no longer new, which will leak/give pagerank to the homepage and the rest of the site.
Keep in mind some issues such as, if your website has 10.000 pages, adding 10-100 new pages would hardly affect your pagerank. But if your site is 20 pages and you add 100 new pages, then you will notice a drop in your pagerank in the first update, then an increase in the next update.
When I add a high amount of new pages to my site, the next thing I do is try to get a few quality backlinks to cover the pagerank leak. This way I would keep the pagerank stable in the first update and then it would increase in the second update.

It’s worth remembering that Page Rank isn’t the only factor. If you have a higher number of pages, then you have the potential to appear for a wider number of searches – provided that there’s original content on the different pages and that each page is optimised for the contents of that page. Let’s face it, people are unpredictable and could search in a 100 different ways for the same thing – having multiple pages means you’ll cover more of these things!

I agree with last post. It’s so exhausting to create pages though for all the long tail keywords…..If it were easy, I guess everyone would do it

I just happened upon this page, and I really agreed with it.
