Hydrogen Generator without PWM

I am not sure why you are using a pwm controller with your hydrogen generator. All it is doing is controlling the power input. It is doing absolutely nothing to aid the process of hydrogen production. So get rid of the 555 timer and just use a battery directly (add a current limit if wanted). For example I got my best result by using a 12 volt SLA Battery two aluminum plates and a cup of salt water (with a lid) I was able to make enough hydrogen that when I ignited it with a lighter it blew off the lid and cracked the plastic cup.

 SPICE Emulation: In theory a PWM could improve volume
by: Jeff at Making-Hydrogen.com

The winner is PWM!

Use PWM instead of applying direct power.

"How can you reduce this wasted power? One clever method is a technique called Pulse Width Modulation (PWM). A conventional linear output stage applies a continuous voltage to a load. This can waste plenty of power (more below)."

"The linear output stage dissipates a jaw-dropping 1.2 W! On the other hand, the PWM output stage (our efficiency champion) delivers the same average power to the load while only consuming 0.2 W!"

A PWM: "looking at this SPICE emulation, in theory it could improve the volume of Hydrogen produced."
