The answer is yes. There are several Zoos which have them... I have a list somewhere which shows which zoo's have which cryptobranchids, how many and the sex ratio, but it'd take some digging to find, and time to list.
Just off the top of my head.
San Antonio, Atlanta, St. Louis, Detroit, Omaha, Cincinnati, Buffalo... maybe other people can fill out the list if I forgot any.
They all have either Japanese, Chinese, or Both, and quite a few other zoos have Hellbenders.
