Abstract
The present disclosure generally provides systems and methods of water electrolysis. The methods include providing a first power between a first terminal plate of a first section and a second segment plate of a second section. The first section is defined by the first terminal plate and a first segment plate. The second section is defined by the first segment plate and the second segment plate. A first power fluctuation is determined from the first power to a second power. The second voltage is transmitted from the first terminal plate to the first segment plate.
Claims10
A method of electrolyzing water, the method comprising:
- providing an electrolyzer stack having a plurality of sections including at least a first section and a second section, wherein the first section is defined by a first terminal plate and a first segment plate and the second section is defined by the first segment plate and a second segment plate;
- providing an input power at a first power value between the first terminal plate and the second segment plate, thereby powering the first and second sections;
- determining a power fluctuation from the first power value to a second power value, wherein the power fluctuation is determined by one or more sensors electrically coupled to the electrolyzer stack;
- and
- transmitting the second power value from the first terminal plate to the first segment plate, wherein transmitting comprises a computing device receiving an input signal from the one or more sensors and transmitting a signal to a power source terminal electrically coupled to the first segment plate to switch from a first power source terminal connection to the second segment plate to a second power source terminal connection to the first segment plate.

- determining a second power fluctuation from the second power value to a third power value, wherein the third power value is greater than the second power value;
- sensing, via at least one sensor, input power transmitted to the electrolyzer stack from an external power source;
- selecting, based on the sensed input power, a power transmission configuration between at least a first configuration and a second configuration, wherein the first configuration comprises transmitting power to the first and second sections via the first terminal plate and the second segment plate, and the second configuration comprises transmitting power to the first section via the first terminal plate and the first segment plate;
- transmitting the second power value from the first terminal plate to the first segment plate, wherein transmitting comprises a computing device receiving an input signal from the one or more sensors and transmitting a signal to a power source terminal electrically coupled to the first segment plate to switch from a first power source terminal connection to the second segment plate to a second power source terminal connection to the first segment plate;
- and
- transmitting the input power between the first terminal plate and the second segment plate, thereby powering the first and second sections,
- wherein selecting the power transmission configuration comprises comparing the input power to one or more thresholds,
- wherein the input power is transmitted in the second configuration when the input power is below a first threshold,
- wherein the input power is transmitted in the first configuration when the input power is below a second threshold, and
- wherein the second threshold is above the first threshold.
