Abstract
A reaction product control system for a fuel cell that includes a controller and a fuel mass flow sensor linked with the controller. An oxidant mass flow sensor is also linked with the controller. Fuel and oxidant control devices are linked with the controller. A fuel and oxidant react to form a reaction product. The fuel mass flow sensor is calibrated for a fuel at an oxidant flow rate and the controller then automatically adjusts the fuel control device when the fuel changes composition to produce the desired reaction product.
