Is there any non-commercial certificate authority capable of issuing valid certificates for web applications? I mean, the certificate must be accepted by browsers, like those of commercial CAs?

Start SSL is a commercial CA that issues standard SSL certificates free of charge. They are accepted by all common browsers, except for very old versions of Opera.

UPDATE: StartSSL/Startcom was sold to WoSign who were caught cheating in 2016 and over the next year or so distrusted by everybody; see the dupes I added to the Q and security.stackexchange.com/questions/127575/… Nov 4, 2021 at 2:37
You can try Let's Encrypt. Is a free, automated, and open certificate authority brought to you by the Internet Security Research Group (ISRG) and sponsored by several companies.
