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 ...
System overview of a fuel cell electric drive Operation of a fuel cell stack Fuel cell stack The fuel cell stack consists of a stack containing up to several hundred fuel cells; it forms the core of the fuel cell system. In each one of these cells arranged in series, a “cold combustion...
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...
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 ...
The response time (Td) depends on the fuel cell stack itself and is usually given on the datasheet. The parameters for flow dynamics (UfO2(peak) and Vu) depend on the dynamics of external equipment (compressor, regulator, and loads) and they are not provided by manufacturers as their valu...

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...
The Fuel Cell Stack block implements a generic model parameterized to represent most popular types of fuel cell stacks fed with hydrogen and air. The block represents two versions of the stack model: a simplified model and a detailed model. You can switch between the two models by selecting th...
Herein disclosed is a cell stack assembly structure for a fuel cell, comprising a plurality of units each of which is composed of a plurality of cell elements laminated in advance and which are stacked and fastened under a predetermined pressure to construct a cell stack assembly. Each of a ...
