Is there any alcohol remaining in beer-stewed chicken? We once tried to use beer instead of water when stewing cubed chicken breast pieces on a lark, and it turned out pretty tasty (surprise, since we don't actually like to drink beer).

However, we were leery about offering the result to the kids since weren't sure how much alcohol would remain in the dish after it's done.

Is there any reliable information about how much alcohol from beer would remain after stewing for 1/2 to 1 hour?
The short answer is:  it depends, on exactly how you cooked the dish, and what other ingredients are in it.

In practice, for a long simmered dish, the answer is going to approach about 20% as documented in the USDA Table of Nutrient Retention Factors Release 6 under the table entry "ALC BEV,STIRRED,BKD/SIMMRD 1.5 HR".  Increasing time to 2.5 hours would go down to about 5%.
