The present invention relates toWith respect to an improved fuel cell stack assembly (10) having at least one fuel cell stack (30) mounted thereon and a metal end plate (40) mounted thereonEach stack isAt least one fuel cellComprises at least one fuel cell stack layer (50) comprising at...
A fuel cell stack (10) assembly comprises an aligned series of multi-function strata (panels) (30) alternating with and interposed between a mating series of electrochemically active strata (12). In a proton exchange membrane (PEM)-type fuel cell stack, the electrochemically active fuel cell st...
A current collecting equipment for a fuel cell assembly of the kind wherein a current collector, a heat resisting insulator and an end plate are in turn being mounted on each end of a fuel cell stack is characterized in that the current collector comprises a plurality of current collecting ...
The heart of the fuel cell system The stack generates the electrical energy used to power the fuel cell electric vehicle. As its name suggests, the component is a stack of fuel cells. In each one of these cells arranged in series, a “cold combustion” process takes place that converts ...
A fuel cell stack assembly includes a fuel cell stack, a first pressure-supporting end plate assembly, a first current collector plate, a second pressure-supporting end plate assembly, a second current collector plate, and a pressure-applying structure. The first pressure-supporting end plate ...
The Membrane, Electrodes, and Gas Diffusion Layers (GDL), combined, constitute the Membrane Electrode Assembly (MEA). When hydrogen and oxygen from the air are present a potential difference of about 1 V (maximally 1.23 V) arises across the membrane. The potential difference is less when curren...
Current step and interrupt tests must be made on a real stack to represent with accuracy its dynamics. The figure below shows the stack response from these tests and the required parameters (Td,UfO2(peak)andVu). The response time (Td) depends on the fuel cell stack itself and is usually...
2.7.3 Fuel Cell Stack Assembly A fuel cell stack is assembled by packing many single cells in series, as shown in Fig. 2.23. The electronic series connection of all these single cells is realized by the electronic conducting bipolar plates. The number of single cells depends on the desired ...
Current step and interrupt tests must be made on a real stack to represent with accuracy its dynamics. The figure below shows the stack response from these tests and the required parameters (Td,UfO2(peak)andVu). The response time (Td) depends on the fuel cell stack itself and is usually...
The fuel-cell stack is being made ready for large-scale production. H₂ Hydrogen serves as the fuel. In the fuel cell, hydrogen molecules are on the anode side. They are made up of electrons and protons. “Collaborating with Bosch will allow us to rapidly ramp up our technology for ind...
