Did you find a particular patent - which is similar to Celani?
A google patent search for assignee:stmicroelectronics hydrogen returns 8000 hits - mostly for fuel cells. Nothing specific turns up . although . It makes sense that in fuel cell R&D - STM could have inadvertently found actual gain, such as when nickel nanopowder was used. From: Teslaalset STMicroelectronics have patents in this field of research I found earlier.
