It still falls under pseudoscience. Even the Sloan School of Engineering has done studies related, practicality of utilizing on board generated hydrogen. Unless you understand the mathematical applications related and the surrounding math related to the I.C.E., will one NOT waste their time with this long and failing concept. It's mostly misconceptions and mis-information and not understanding the huge amount of science and physics that preempt the theories attempted. Mostly people don't wont to be wrong especially when there has been a personal or financial vested interest. Hence defensiveness and stubbornness prevails. Here is more on this phenomenon:

Also, utilizing a incredibly fast burning fuel like Hydrogen in very high compression engine, has very little validity for a productive outcome.
