摘要:
An illustrative example electrical power generating system includes a fuel cell power plant that is configured to generate electrical power. The fuel cell power plant includes a cell stack assembly including a plurality of fuel cells that are configured to generate electrical power based on a chemical reaction. A coolant network is configured to carry fluid toward the cell stack assembly where fluid in the coolant network can become heated by absorbing heat from the fuel cell power plant. The coolant network includes a thermal hydraulic engine that is configured to generate electrical power. The coolant network is configured to carry the heated fluid to the thermal hydraulic engine where the heated fluid can be used for generating electrical power. The coolant network is configured to carry a reduced temperature fluid from the thermal hydraulic engine back toward the cell stack assembly.

Invented is a Resource Tower that uses water electrolysis to separate out its elemental and purified H2 hydrogen gas and O2 oxygen gas. These gases form a pressurized flow for electricity generation for distribution and transport to heights atop the Resource Tower. Core advancements of this invention are the use of fuel cells at the top of the Resource Tower to electrochemically combine hydrogen gas and oxygen gas to produce electricity, heat, and water. The Resource Tower distributes the electricity, converts heat and water to steam to generate additional electricity for distribution, and ultimately coalesces the steam back to water at a height. The water that falls under acceleration of gravity from atop the Resource Tower is used to generate additional electricity for distribution. In addition to multiple sites of electricity generation for distribution, the purity of hydrogen gas and oxygen gas from water electrolysis is retained and the water resulting from the Resource Tower is purified and potable for distribution.

An electrical power supply system has a fuel cell module and a battery. The fuel cell can be selectively connected to the battery system through a diode. The system preferably also has a current sensor and a controller adapted to close a contactor in a by-pass circuit around the diode after sensing a current flowing from the fuel cell through the diode. The system may also have a resistor and a contactor in another by-pass circuit around the diode. In a start-up method, a first contactor is closed to connect the fuel cell in parallel with the battery through the diode and one or more reactant pumps for the fuel cell are turned on. A current sensor is monitored for a signal indicating current flow through the diode. After a current is indicated, a by-pass circuit is provided around the diode.

摘要:
An exemplary method includes of operating a fuel cell at a first power output level that includes a plurality of operation parameters. Each operation parameter has a value to satisfy a first power demand. A change between the first power demand and a second power demand is determined. At least a first one of the operation parameters is maintained at a value corresponding to the first power output level or at an intermediate value while at least a second one of the operation parameters is changed to a value corresponding to a second power output level to satisfy the second power demand. The first operation parameter is delayed from changing to a value corresponding to the second power output level until a predetermined criterion is met.
